プリントヘツド。[Claims for Utility Model Registration] A head board having print media and their drive circuits arranged in rows in the longitudinal direction of the board on a heat sink, and a terminal portion formed on the back surface of one side of the head board. A holding cover that fixes the connection board to be overlapped with the terminal part formed on the side surface and presses the overlapping part of the terminal part via an elastic pressing body is pressed from above the connection board. The thermal print head is screwed to a heat sink, and the drive circuit is attached to the head board by resin coating, and the resin coating part has a cross-sectional shape in which the side facing the printing medium has the elasticity. A thermal print head characterized by being formed lower than the side located on the pressing body side.
