Abstract
A thermal head includes a substrate, a plurality of heat generating portions, electrodes, pads, driving ICs, and a wire. The plurality of heat generating portions are positioned on the substrate and arranged in a main scanning direction. The electrodes are positioned on the substrate and electrically coupled to each of the plurality of heat generating portions. The pads are positioned on the substrate and coupled to the electrodes. The driving ICs drive the heat generating portions. The wire couples the driving ICs and the electrodes to each other. The thermal head according to the present disclosure includes a plurality of the pads. At least one of the pads is a multi pad that has a first region to which the wire is connected and a second region to which each of a plurality of probes is connected.
