PURPOSE:To manufacture a resonator of small size near the shape of an element by overlapping a lower pedestal and an upper pedestal so as to attain ease of alignment of the element. CONSTITUTION:The synthetic resin made lower pedestal 9 a part of which is exposed is formed incorporatedly to an electrode 7a so that one lead electrode of a rectangular piezoelectric element 1 one end of which is supported by the hook shape electrode 7a is brought into contact with the electrode plate 7a. After the element 1 is mounted on the pedestal 9, the upper face of the pedestal 9 is covered by the synthetic resin made upper pedestal 12 formed incorporatedly with the hoop electrode plate 7b similarly as the pedestal 9 and the case for the element 1 is formed by incorporating the pedestals 9, 12 while the other lead electrode of the element 1 and the electrode plate 7b are brought into contact with each other. Then the electrode plates 7a, 7b are disconnected from electrode plate connecting parts 10a, 10b. |
