In the operation button structure, pressing switch contact portions are satisfactorily pressed by a tilting button operating member even if the button operating member and the switch contact portions are a long distance apart from each other or positions of the switch contact portions vary. When an operator's finger presses a right end of a button operating member, a pressing portion on a right side moves in a direction perpendicular to an upper surface of a substrate, whereby a switch contact portion on the right side is pressed. On the other hand, when the finger is lifted from the button operating member, the pressing portion retracts from the switch contact portion by a connecting portion formed in a shape having elasticity.
