Provided is thermal printer in which positioning precision between a platen roller and a thermal head is enhanced, thereby being capable of positively arranging heating elements within a heating element allowable range. The thermal printer comprises: a through-hole (35) which makes a head support member (12) movable with respect to the main 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), positions of 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 main 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.
