Claims

[Claims for Utility Model Registration] (1) An electrically insulating substrate in which a plurality of heating resistors are arranged on one main surface close to the side end surface, and a side end surface other than the above-mentioned side end surface of the board as a heat dissipating member. 1. A thermal head, characterized in that the thermal head is adhesively fixed to the heat dissipating member while being positioned in contact with an abutment portion formed in the heat dissipating member. (2) The thermal head according to claim 1, wherein a groove is formed at the base end of the stopper provided in the heat dissipating member.
