    摘要： The present disclosure provides a thermal print head. The thermal print head includes: a substrate; a glaze layer, disposed on the substrate; and a wiring layer, disposed on the glaze layer. The wiring layer includes a plurality of bonding pads. The plurality of bonding pads are divided into a plurality of groups. Each of the plurality of groups includes a first bonding pad, a second bonding pad, a third bonding pad and a fourth bonding pad. A first group of the plurality of groups is adjacent to a second group of the plurality of groups along a first direction. The second bonding pad of the first group is located between a center of the first bonding pad of the first group and a center of the third bonding pad of the first group along the first direction.

    摘要： The present invention provides a heater capable of prohibiting failures of a substrate and a heat resistor. The heater of the present invention includes a substrate in a longitudinal shape, a heat resistor formed on the substrate, and an electrode for resistor formed on the substrate and connected to the heat resistor. The heat resistor includes a first elongated portion, and the first elongated portion extends along a long side direction of the substrate and is disposed in a side in a first short side direction, which is one of short side directions of the substrate. A ratio of a distance between the first elongated portion and an edge of the substrate on the first short side direction, to a thickness of the substrate is more than 0 and less than 1.75.
