PROBLEM TO BE SOLVED: To eliminate an extra junction between a flexible printed circuit and a switch and improve reliability. SOLUTION: A membrane switch is directly formed on an FPC (contact circuit body) harness 2. The conductive pattern 2b of the FPC harness 2 is partially disrupted. A spacer forms a gap between the conductive pattern 2b of the FPC harness 2 and the contact point 3b of a membrane 3. When pressing force is applied to the membrane 3, the membrane 3 is warped, and the contact point 3b is brought into contact with the upper face of the disrupted portion of the conductive pattern 2b into a conductive state. When no pressing force is applied to the membrane 3, the contact point 3b is separated from the upper face of the disrupted portion of the conductive pattern 3 into a nonconductive state.
