PROBLEM TO BE SOLVED: To provide a push-button member that is capable of curving or bending in any direction so as to be able to correspond to complex curvature of the enveloping face of the keytop. SOLUTION: This is a push-button switch member having a plurality of protruded push-button parts 1 that are formed by mold drawing of the resin film 6. The width of the connecting part 4 connecting each protruded push-button part 1 is made a length of 50% or less of the length of its side in the case the shape of the top face of the keytop of the protruded push-button part 1 is rectangular, the axial length of the ellipse in the case of ellipse, and the diameter in the case of circle, and 1 mm or more. It is desirable that a polyester system resin film having a thickness of 100-150μm is used as the resin film 6. The protruded push-button part connected can be divided in plural blocks.
