To make a crystal resonator small in size and light in weight by using one end of a lead frame as the electrode of one terminal part, and using another end as the electrode of the other end part, while making the nearby part of a rectangular corner part to be parallel in the longitudinal direction of a cylinder-type crystal resonator and pulling the inner part of mold resin to the other end.

A fixing part 15 is connected to a lead frame 13 with a frame 17. The connection part of the fixing part 15 to the frame 17 and the connection part of the lead frame 13 to the frame 17 are bent. The frame 17 is arranged in the rectangular corner part 18a of a mold. The lead frames 13 and 14 are integrally constructed and are formed in a prescribed shape by pressing from a band member and bending work is simultaneously executed by pressing. An electrode 13b (13a) is connected to the terminal 2 of a cylinder type crystal resonator and an electrode 14b (14a) is connected to a terminal 2'. One end of the lead frame 13, where the two terminals 2 and 2' of the cylinder type crystal resonator 1 are fixed, is set to be the electrode of one end part and the other part is set to be the electrode of the other end part, by making the nearby part of the rectangular corner part to be parallel to the longitudinal direction of the cylinder type crystal resonator 1 and pulling the inner part of mold resin to the other end.
