Abstract
A method for manufacturing a thermal head, including: forming a resistance heating element and an electrode on an insulating substrate, the resistance heating element emitting heat by a current flowing the resistance heating element, the electrode being connected to the resistance heating element; forming a corrosion prevention layer on the resistance heating element and the electrode; annealing the resistance heating element; adjusting an electrical resistance of the resistance heating element; and forming a protective layer on the corrosion prevention layer, the protective layer having glass as a main component. The annealing is implemented prior to the adjusting. The forming the corrosion prevention layer is implemented prior to the annealing.
