PROBLEM TO BE SOLVED: To provide a cover of small-sized electronic appliances, wherein a liquid is so prevented from penetrating its inside for an electronic appliance from its heat radiating through holes, even when the liquid is dropped carelessly on its top surface to prevent electric circuits from breaking. SOLUTION: The cover for electronic appliances is subjected to molding by using a synthetic resin material. In at least one of its top-surface plate 2 and its rear-surface plate 3, heat radiating through holes 15, 16 are formed in the nearly horizontal direction. Further, on the upper-side wall and the lower- side wall of each of the heat radiating through holes 15, 16, respective step portions protruded from the walls are formed.
