That Support Society
The most significant social responsibility that the Sansha Electric Manufacturing Group has as amanufacturer is to conduct manufacturing that is valuable to society. We support society by providing
power semiconductors for many different power supplies and industrial power supplies for a wide rangeof industries, from high to low power, in Japan and overseas under the concept of the integration oftechnologies for power semiconductors and for power supplies.
