Abstract

PURPOSE:To rapidly reduce the increase in the resistance value of a connector, disconnection, leakage of a thermal head by forming the thin film coating of the connector of a lead layer and an energizing layer formed at the special positions to a lead layer of specific material (such as aluminum, nickel, gold, tin, etc.). CONSTITUTION:Lead layers 51, 55 are connected with metal different from an energizing layer at the position isolated by the prescribed distance from the facing gap of energizing layers 41, 45 pair formed of high melting point metal. A thin film coating 17 is formed on the connector of the layers 41, 45 with lead layers 51, 55, and the material of the coating 7 is selected from oxidized silicon, nitrided silicon, oxidized aluminum, oxidized tantalum or oxidized chromium.
