Abstract

PURPOSE:To enable a high speed type printing operation while reducing disconnection, by dividing resistance heaters into a pluraity of groups, forming an electrode by each resistance heater at the one side of each group of the resistance heaters, and forming a common electrode for the resistance heaters at the other side. CONSTITUTION:A lot of resistance heaters 2 are arranged in a line at the center of a dielectric substrate 1. The heaters 2 make groups 3. Electrodes 4 at the one side of the heaters 2 are arranged alternatively right and left by each group 3. The electrode 4 is connected to an independent tape carrier by each group. Owing to this alternative arrangement, a generated heat can be dispersed. A common electrode 5 is formed so as to surround the heaters 2 and each electrode 4. The common electrode 5 is spaced from each electrode 4, and connected to each heater 2.
