1. A power-control device comprising:

  • a sensor unit including a sensor electrode, a conductive substrate that has an area larger than that of the sensor electrode, and a case formed of an insulating material, the conductive substrate being provided inside the case, the sensor electrode being electrically connected to the conductive substrate, the sensor unit that generates capacitance between a human body and a surface of the case when the human body touches the surface of the case; and

    a detection unit that detects the capacitance and outputting an activation signal used to supply power.
