A television game machine includes a housing having an air intake and air exit in side surfaces, and forms an air flow passage in a space of air flow on a line connecting between the air intake and the air exit. A heat-radiating member formed with heat-radiating fins is attached in a state electrically insulated from a semiconductor device mounted on the printed board in order to transfer heat generated from the semiconductor device. The heat-radiating member is arranged related to the semiconductor device and printed board such that the heat-radiating fins are along the air flow passage. When ambient air is taken through the air intake and caused to flow through the grooves between the heat-radiating fins of the heat-radiating member to be released outside through the air exit, a fan releases the heat dissipated from the heat-radiating fins together with flowing air to an outside.
