PROBLEM TO BE SOLVED: To provide a control key with variable resistance which can be small-sized, with which a smooth operational touch can be felt, and which can reduce the number of components. SOLUTION: The control key with variable resistance uses a bamboo shoot spring 6 that is a conductive contact disposed while facing a variable resistance pattern 3, on an upper surface of an insulated substrate 2 between the insulated substrate 2 including a circuit pattern arranging variable resistance and an operating member 5. Thus, the control key of the present invention can be small-sized in comparison with a conventional control key with variable resistance, and a smooth operational touch can be obtained.
