1. A high-voltage generating circuit that drives a laser puncturing unit that oscillates laser light and punctures skin, the high-voltage generating circuit comprising:

  • a capacitor that is charged with an electric charge and supplies power to the laser puncturing unit;

    a boost circuit that supplies a current to the capacitor;

    a voltage measuring section that measures a voltage of the capacitor; and

    a control section that controls the boost circuit based on a command from a user or the voltage of the capacitor,wherein the control section starts charging the capacitor with a current of a first value at a first timing, and starts charging the capacitor with the current of a second value higher than the first value at a second timing later than the first timing.
