HEATER AND METHOD FOR MANUFACTURING THE SAME

摘要

A heater (A1) is provided with a substrate (1); a heat resistive element (2) formed on the substrate (1); and an electrode (3), which is electrically continuous to the heat resistive element (2) and contains a metal component. The heater (A1) is also provided with a diffusion suppressing layer (4), which is brought into contact with at least a part of the electrode (3), and suppresses diffusion of the metal component from the electrode (3). Removal of the heat resistive element (2) and the electrode (3) is prevented by suppressing the diffusion of the metal component from the electrode (3) to the heat resistive element (2).
