ABSTRACT:
A thermal print head comprises a heat resisting resin film and resistive heating layers and metal circuit layers on the film, the metal circuit layers connected to the resistive heating layers respectively. The film is supported on a heat sink substrate provided with a flat surface and corner sections formed at the both sides of the flat surface, the resistive heating layers positioned over the flat surface. The heat sink substrate supports the film to prevent the resistive heating layers from electrical resistance value fluctuation due to bending of the film.
