ELECTRONIC APPARATUS

The electronic apparatus has: a flat-shaped main body chassis provided with a motherboard; a switch provided at an end portion of the motherboard; a button for pressing an actuator of the switch; a restriction section that restricts the button from rotating around a contact portion when the button presses the actuator; and a button opening formed in a side wall of the main body chassis at a position shifted to a higher level than the switch. The button includes: an operation section exposed through the button opening; an arm portion that extends to a position facing the actuator; and a fin piece that protrudes. The restriction section is provided in such a manner as to face the fin piece at a position vertically shifted to a lower level then the fin piece.
