PROBLEM TO BE SOLVED: To facilitate the alignment by photolithography in the pattern formation of resistors and to prevent the generation of inferior products caused by the disconnection of the resistors at the interface of a common electrode part and a glaze glass layer. SOLUTION: A thermal head is characterized by that the width WR of the resistors Ra formed in the longitudinal direction of a common electrode part M is equal to or less than the width WM of the common electrode part M and the width WM of the common electrode part M is below the width WC of a common electrode C. In this case, the width WC of the common electrode C is desirably 2,000μm or less.
