PROBLEM TO BE SOLVED: To make a device small-sized, lightweight, and small in the number of components and to suppress the shortening of the life, etc., due to a temperature rise by accelerating the cooling of a heating element. SOLUTION: This equipment is equipped with a means which generates an air flow in a housing containing the heating element 10 as an electronic equipment component and formed by engaging a front cover 1 and a rear cover with each other and a means which narrows an air flow passage on the internal surface of the housing, covering the heating element 10, where the heating element is arranged; and the means which narrows the air flow passage is provided facing the heating element 10 and a projection part of a member 8 which reinforces the structure of the housing and its shape crosses the air flow passage at right angles. The housing is provided with a lower intake 7 and an upper outlet 9 as parts of the air flow passage and a means which generates an air flow is a fan 5.
