Abstract: A thermal head capable of decreasing the possibility of causing wrinkles in a recording medium is provided. A thermal head includes: a substrate; a heat generating portion disposed on the substrate; a driving IC disposed on the substrate and controlling actuation of the heat generating portion; a covering member covering the driving IC; and a projection portion disposed on the substrate and making contact with a recording medium. The substrate includes a first region and a second region in a plan view, the first region being defined by extending an area where the driving IC is disposed in a sub scanning direction and the second region being an area other than the first region. The projection portion is disposed on the second region closer to the heat generating portion than the area where the driving IC is disposed.

Abstract: A thermal head includes a substrate, a glass-made thermal storage layer disposed on one main surface of the substrate so as to extend to an edge of the substrate; electrodes disposed on or above the thermal storage layer apart from the edge of the substrate; heat-generating resistors disposed above the thermal storage layer apart from the edge of the substrate, the heat-generating resistors being connected to the electrodes; and a first covering layer disposed on or above the electrodes and the heat-generating resistors. The first covering layer extends from atop the electrodes and the heat-generating resistors toward atop the thermal storage layer on the edge of the substrate, and a protection film is disposed on or above the first covering layer disposed on or above the electrodes and the heat-generating resistors and an edge of the protection film is not disposed above the edge of the substrate.
