Operability of a heating cooker having a heating unit in a top plate is improved. After power-on, a light emission control unit causes the operation unit light-emitting element of an operable operation inhibition releasing key to be lit so that only the key is displayed and the other keys are less visible. Thus, the heating cooker is changed into a lock state. When the operation inhibition releasing key is operated in the lock state, at least one electrostatic touch key other than the operation inhibition releasing key is made operable and the operation unit light-emitting element is lit. Alternatively, in the above structure, the operation unit light-emitting element of the operable operation unit is lit in a first light-emission color, and the operation unit light-emitting elements of the inoperable operation units are lit in a second light-emission color different from the first light-emission color. Thus effective operation can be guided. |
