MARUWA CO.,LTD

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.

Business　Domain
Having the ceramic material technology as its core, our business expands in a wide range of areas including four fields: ceramics, electronic components /devices, quartz glasses, LED lightings.

• Plugged-in Innovation

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.
