Abstract
An electronic part such as a dielectric duplexer or filter is provided which comprises a dielectric ceramic block having a pair of opposite first and second side surfaces and an end surface meeting the first and second side surfaces nearly at right angles, an extension-electrode forming notch formed in the end surface so as to have an open end at the first side surface, a dummy electrode-forming notch formed in the end surface so as to have an open end at the second surface, the extension electrode-forming notch and the dummy electrode-forming notch corresponding in shape and position when observed in the direction in which the first and second side surfaces are opposed, an extension electrode formed in the extension electrode-forming notch, and a dummy electrode formed in the dummy electrode-forming notch. A method of forming an electrode of such an electronic part is also provided.
