1. A heating/cooking equipment, comprising:

  • a top plate;

    a heating unit configured to heat an object to be heated placed on the top plate;

    at least one electrode arranged under the top plate;

    a capacitance detecting unit configured to detect an electrostatic capacitance of the electrode; and

    a microcomputer configured to detect boiling over of material cooked in the object based on a value of the electrostatic capacitance of the electrode received from the capacitance detecting unit, and to control a heating operation of the heating unit based on a detection result of boiling over, whereinthe top plate is directly connected to a circuit potential, a ground potential, or a potential above the ground potential, andthe capacitance detecting unit detects a change in the electrostatic capacitance of the electrode by exploiting capacitive coupling between the electrode and the circuit potential, the ground potential, or the potential above the ground potential to which the top plate is connected.
