PURPOSE:To attain ease of positioning of a ceramic resonator and also to form a small-sized shape close to the element shape by combining two case constituents as one body and folding a metallic plate being an input/output electrode along the case constituent. CONSTITUTION:The metallic plate 7 consists of one electrode part other than the main vibrating part of a ceramic resonating element 1, a connecting part 7a and an external input/output electrode part 7b. The case constituent 8 is incorporated with an element connecting part 7a of the metallic plate 7, made of a resin or an insulator at the same face of which a projected part 8a is projected by the same thickness' share of the metallic plate 7 for the part without the electrode 2 of the ceramic resonating element 1, in butting the two case constituents 8 while turning them by 180 deg., they are incorporated so as to constitute the outer package. The ceramic resonating element 1 is placed along the connecting part 7a of the metallic plate 7 as shown in the arrow to the case constituent 8. Moreover, the electrode 7b is bent and wound on the case constituent 8 combined in this way. Through the constitution above, the positioning is made easy and miniaturization is attained. |
