ABSTRACT:
An electronic apparatus, including a plate-like member, enclosing a heat-accumulating material of latent heat type within an inside thereof; a semiconductor element, being connected with the member, thermally; and a housing covering the semiconductor element and the member. A surface of the member, in contact with the semiconductor element, is provided with recess-portions in plural numbers thereof, each being recessed in a direction of the heat-accumulating material of latent heat type, so as to enclose the heat-accumulating material of latent heat type into the recess portions. The plate-like member and the housing are connected with each other, thermally, thereby providing a cooling device, being able to cool the electronic circuit component(s) building up the electronic apparatus, as well as being superior in operability.
