A button switch structure for a mouse is provided to extend the lifespan of the mouse by guaranteeing duration of an FPC(Flexible Printed Circuit) and a third pattern as stress according to deformation of an insulation member is restricted to a negligible level while the FPC and the third pattern are deformed as long as a predetermined distance. A PCB(Printed Circuit Board)(20) forms a first and second pattern(21,22) at an interval. The insulation member(25) forms a connection space(26) to a position corresponding to the position of the first and second pattern while being placed to an upper side of the PCB. The FPC(30) forms the third pattern(31) corresponding to the position forming the first and second pattern while being placed to the upper side of the insulation member. Thickness of the insulation member is 0.1-0.3 millimeters. As a pressing tool(40) is placed to the upper side of the FPC, the third pattern of the FPC is pressed by a pressing tool.
