Abstract: An end surface (5, 5b) of a cylindrical ceramic body (2, 2b) is dipped into a bath of metal paste (15), so that an opening (10, 10b) formed in the end surface is closed by the metal paste. Then an air pressure difference is provided such that the air pressure in an inner space (9, 9b) of the ceramic body is lower than the air pressure in an outer space (19, 19b) surrounding the ceramic body, whereby the surface of the metal paste located in the inner space is upwardly moved. Thus, a substantial region of an inner peripheral surface (7, 7b) of the ceramic body is brought into contact with the metal paste. Then the pressure difference is cancelled so that a metal paste film (21, 21a, 21b) for serving as an inner electrode (3, 3a, 3b) of a cylindrical capacitor (1, 1a, 1b, 1c) is formed on the inner peripheral surface.
