A thermal printhead includes plural groups of drive ICs (DrIC1-14), a plurality of main conductor wirings (31-34) for transmitting signals to the drive ICs in the respective groups, and a plurality of auxiliary conductor wirings (41-43) respectively provided to accompany the main conductor wirings for providing conduction between the drive ICs in adjacent groups. The main conductor wirings and the auxiliary conductor wirings respectively include severable sites (a-f) for severing electrical conduction of the main conductor wirings and the auxiliary conductor wirings. A plurality of recovery wiring portions (32a-34a and 41a-43a) are provided to the respective severable sites in parallel thereto. Each of the recovery wiring portions includes a pair of pads spaced from each other.
