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 print head is screwed to a base board, and the terminal part of the head board is partially formed in the intermediate part in the longitudinal direction of the board, while the terminal part of the head board is formed on both sides of the terminal part. The ground wiring pattern of the drive circuit and the ground wiring pattern are led out from the printing medium, are wrapped around the outside of the ground wiring pattern, and have their edges positioned between the ground wiring pattern and the terminal portion. A common wiring pattern is formed in two rows along the longitudinal direction of the board, and the terminal part of the connection board is connected to the terminal part of the head board, the ground wiring pattern, and the common wiring pattern. and a print head overlapping an edge of the common wiring pattern located between the terminal portion and the ground wiring pattern.
