A heating cooking device includes a top plate, a heating unit, a touch key including a first electrode and a second electrode, an input unit for applying an alternating current (AC) voltage to the second electrode and for outputting a voltage changing according to a change of the AC voltage when the first electrode is pushed, a detector for outputting a first signal if the voltage output from the input unit changes from the reference value to the first value, an operation judging unit for outputting a second signal according to a rate of change of the voltage output from the input unit, and a controller operable to perform control of the heating unit based on the first and second signals. The controller is operable to perform control of energization of the heating unit if the controller does not receive the second signal after receiving the first signal, and not to perform the control of the energization of the heating unit if the controller receives the second signal after receiving the first signal.
