A thermal head includes a substrate; a heat generating section disposed on the substrate; an electrode which is disposed on the substrate and is electrically connected to the heat generating section; and a connector including a fixing ping electrically connected to the electrode, a movable pin which holds the substrate between the movable pin and the fixing pin, and a connection pin which connects the fixing pin and the movable pin. The movable pin includes a movable section which is bent or curved and a contact section making contact with the substrate. The movable pin is disposed so as to protrude from the connection pin beyond the fixing pin. The contact section is located closer to a connection pin side than a tip end of the fixing pin.

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.

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.
