Abstract: An electric device capable of suppressing an influence of variation of a consumed current on a superimposed signal is provided. An electric device which transmits a superimposed signal obtained by superimposing a data signal on the operation signal according to a state of an operating element to the outside, includes a current consuming part configured to consume a current, and a current control part configured to control current consumption in a circuit including the current consuming part such that current variation of the superimposed signal following variation of the consumed current in the current consuming part is suppressed.
