PROBLEM TO BE SOLVED: To improve an isolation characteristic in a ceramic device which is mainly used for high frequency use. SOLUTION: The device is provided with a ceramic substrate 1, inner electrodes 2 which are disposed in the ceramic substrate 1 and form a prescribed circuit, and terminal electrodes 3 which are electrically connected to the inner electrodes 2 on the outer surface of the ceramic substrate 1. The surface of the ceramic substrate 1 positioned between the terminal electrodes 3 is made rough. COPYRIGHT: (C)2007,JPO&INPIT
