Thermal head and thermal printer equipped with the thermal head

摘要

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.

1. A thermal head, comprising:
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 under conveyance, wherein the substrate comprises a first region and a second region in a plane 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, wherein the projection portion is disposed on the second region closer to the heat generating portion than the area where the driving IC is disposed, wherein the projection portion is separated from the covering member in a plan view.
