Abstract
A thermal head includes a substrate, a heat-generating portion disposed on the substrate, electrodes disposed on the substrate and electrically connected to the heat-generating portion, a driver IC disposed on the substrate and electrically connected to the electrodes, and a covering member covering the driver IC. In plan view, a center line of the driver IC extending in a main scanning direction and a highest position of the covering member are located farther form the heat-generating portion than a center line of the covering member extending in the main scanning direction.
