A thermal head includes a substrate; a plurality of heating elements disposed on the substrate; a plurality of electrodes disposed on the substrate and electrically connected to the plurality of heating elements; a connector disposed adjacent to the substrate and including a plurality of connector pins including connection portions, each of which is electrically connected to a corresponding one of the plurality of electrodes, and a housing containing the plurality of connector pins; and a covering member covering the connection portions on the substrate. The housing includes an opening facing away from the substrate. The covering member includes a first portion located on the substrate and a second portion located on the housing. The second portion includes a first protrusion protruding toward the opening in a plan view.

Thermal head and thermal printer

A thermal head capable of reducing a possibility of separation of a connector is provided. A thermal head includes a substrate; a plurality of heat generating portions disposed on the substrate; a plurality of electrodes which are disposed on the substrate and are electrically connected to the plurality of heat generating portions, respectively; and a connector including a plurality of connector pins which pinch the substrate and are electrically connected to the plurality of electrodes, respectively, and a housing for containing the plurality of connector pins. The housing is disposed adjacent to the substrate in a sub-scanning direction, and the housing includes a support portion disposed under the substrate. This can reduce a possibility of separation of the connector.

To provide a thermal head in which separation of a protective layer is unlikely to occur. A thermal head Xincludes a substrate, a heat-generating portiondisposed on the substrate, electrodesanddisposed on the substrateand electrically connected to the heat-generating portion, and a protective layerwhich covers the heat-generating portionand part of the electrodesand. The electrodesandeach includes a first region Rwhich lies below a depth of 150 nm from the surfaceorlocated on the protective layerside, and the first region Rcontains oxygen. It is possible to suppress separation of each of the electrodesandfrom the protective layer
