A terminal electrode 10 to connect a conducting wire is formed, with plating, on the surface of an electrode formed on the surface of the ceramic and made of an electrode material containing a glass component by the terminal electrode forming method. This method includes a first gold plating layer forming step of forming a first gold plating layer on the surface of the electrode with the plating by use of a plating liquid having a pH of 6 to 8, a nickel plating layer forming step of forming a nickel plating layer on the surface of the first gold plating layer with the plating, and a second gold plating layer forming step of forming a second gold plating layer on the surface of the nickel plating layer with the plating.
