A hand-held game machine (10) includes a horizontally-long rectangular housing (12), and the housing is covered with a cover (14) almost entirely. Each of top main surfaces of the housing and the cover has a plane shape of pincushion, and thus, the top main surface of the housing forms a lower inclined surface (26) connecting a lower side surface (22) and the top main surface of the housing. On the top main surface of the housing, a cross key (16) and an A button (18a), and a B button (18b) are provided, and on the lower inclined surface (26), a start switch (28) and a select switch (30) are arranged. On left and right edges of an upper side surface (20) of the housing, a left switch (32L) and a right switch (32R) are arranged. As to each of the left switch and the right switch, a switch portion is formed at one end nearer to a center of the housing in the horizontal direction, and a pin is provided at the other end opposite thereto. The pin is inserted into a bearing formed on the housing to function as a pivot at the other end of each of the left switch and the right switch.
