PROBLEM TO BE SOLVED: To reduce unevenness in a main scan direction in a thermal print head in which a power supply electrode extends between adjacent heating resistor parts.SOLUTION: A thermal print head has heating resistor parts 36 arranged at an interval on an insulating substrate, each extending in a direction crossing an arrangement direction. A dissimilar metal film 41 is provided between the adjacent heating resistor parts 36. Electrodes thicker than the dissimilar metal film 41 are connected to both ends in a sub scan direction of the heating resistor parts 36 and both ends in the sub scan direction of the dissimilar metal film 41. |
