PURPOSE:To prevent an irregularity in local heat transfer of a board and a heat dissipation plate and to improve printing quality by adhesively integrating a heat dissipation member of a curved shaped recessed at a securing surface side or flat plate shape. CONSTITUTION:A heat generating resistor array 13 is formed near one end on a head board 12, a driving circuit 14 is mounted near its opposite side end to the row 13, and inputs data to be printed and various control signals. The board 12 is secured through a rectangular heat dissipating plate 15 made of a metal material having excellent heat conductivity such as aluminum and an adhesive layer 17 made of adhesive or self-adhesive. |
