PROBLEM TO BE SOLVED: To provide a thermal printer in which positioning precision between a platen roller and a thermal head is enhanced, thereby positively arranging heating elements within a heating element allowable range. SOLUTION: The thermal printer comprises: a through-hole 35 which makes a head support member 12 movable with respect to the body frame 10; a regulating surface 36a, which is formed in the head support member 12, serving as a positioning reference portion when a thermal head 11 is positioned and fixed to the head support member 12, and positioning, at a time of mounting a platen roller 13, the heating elements 14 with respect to the platen roller 13 through abutment of the platen roller 13 to the regulating surface 36a; and a plate spring 47 which urges the head support member 12 in a direction of making a bottom wall 10e of the body frame 10 spaced apart from the head support member 12 so that the regulating surface 36a abuts on the platen roller 13, in which the regulating surface 36a is formed in a flat surface, and a normal line direction of the regulating surface 36a coincides with a Z direction.
