| 内容： | A gas sensor is equipped with a built-in ceramic heater. The gas sensor detects the concentration of a predetermined gas component contained in the exhaust gas. The ceramic heater has a heater base member made of ceramic, a heating element formed in the inside of the heater base material, and a pair of external electrode pads that is electrically connected to the output terminals for the outer leads. The external electrode pads, the heating element, and the heater leads are made of base metal. The outer surface of each external electrode pad is covered only with a dense protective film made of noble metal such as gold(Au), silver(Ag), platinum(Pt), rhodium(Rh), and palladium(Pd). |
