ABSTRACT:
A thermal head comprises an insulative substrate, heat-generating resistor elements mounted on the insulative substrate, a driver IC mounted on the insulative substrate for driving the heat-generating resistor elements, a heat radiating member connected to the insulative substrate for radiating heat generated by the heat-generating resistor elements, and a flexible circuit board for supplying power to the driver IC. The flexible circuit board has conductor layers interposed between insulating layers, a first portion connected to the heat radiating member, and a second bent portion having one of the conductor layers electrically connected to the insulative substrate.
