With the long-cultivated technologies since our founding, we produce and fabricate materials with superior properties. In addition, we apply our elemental technologies such as circuit design, experiment evaluation, mounting, and simulation, etc., to those material technologies in order to send our own unique products to the world. Manufacturing the products from its very beginning to end makes it possible for us to expand our business in various areas.
Having the ceramic material technology as its core, our business expands in a wide range of areas including five fields: Automotive Related Business Division, Information/Communication Related Business Division,Semiconductor Related Business Division, Industrial Equipment Related Business Division,Lighting Related Business Division.
Ceramic Component Business
Ceramic substrates used as components of electronic circuits, ceramic materials and parts used for optical communication and ultra high purity SiC components for semiconductor manufacturing.
Countermeasure parts for noise elimination, EMC (Electromagnetic Compatibility), and high-frequency parts for information equipment using radio waves.
High purity and high precision quartz glass parts for semiconductors, compound semiconductors, and optical fiber fields
Lighting Equipment Business
LED lighting equipment and LED modules for exteriors and interiors of public buildings including street lights.
Products Made with Ceramic + α Technology
The MARUWA products are made of technology obtained through new research and development and business acquisition based on ceramic materials and manufacturing technology. We are steadily developing new technologies.
MARUWA products support the ever-evolving electronics technology from the background.
Diffusion of IoT · AI
Next generation 5G mobile communication system, next generation's mobility autonomous driving. Due to technological advances, the era will come where everything is networked. MARUWA's ceramic products and high frequency components with excellent heat dissipation will play an important role in the arrival of the IoT era.
Energy and Power Savings
Taking into account the global environment and realizing a sustainable society, it is becoming inevitable to save energy and power in many fields. For example, to operate a complicated electronic/electric circuit stably with lesser electricity requires to dissipate the generated heat while it is in operation.
In addition to the excellent electrical performance and reliability of ceramics, MARUWA realizes high heat dissipation performance in ceramics as in metals. They dissipate heat on circuit boards, etc.
Miniaturizing and multifunctioning
Miniaturing and multifunctioning electronic and electric equipment mean that the electronic circuit becomes complicated, and it will have to contain ICs and electronic parts in a limited space. That requires the miniaturization of electronic components and countermeasures against the noise. In addition to unique ceramic material technology, MARUWA contributes to the evolution of electronic and electrical equipment with the ceramic product technology of adding layers of substrates with complicated circuit patterns.
EMC countermeasure parts such as capacitors, inductors, and EMI filters eliminate the noise.
