Existing pain-relief devices have the problem that the use thereof requires specialized knowledge of Eastern acupuncture, e.g. meridians and acupuncture points, making it difficult for ordinary people to use said devices to relieve pain in painful areas. The disclosed pain-relief device is provided with: a small camera that, in step ST3, takes a picture of a painful area and outputs a camera signal; a camera-signal processing circuit that processes the camera signal from the small camera; a display unit that, in step ST4, displays an image of the painful area, obtained via the processing of the camera signal in the camera-signal processing circuit; and a semiconductor laser that, in step ST7, is driven by a laser-driving circuit and irradiates the painful area with heat-producing laser light.
