<P>PROBLEM TO BE SOLVED: To provide a surface-mounted crystal oscillator capable of enhancing quality, reducing manufacturing costs, and improving productivity while achieving downsizing, and a method for manufacturing the oscillator. <P>SOLUTION: There is provided a surface-mounted crystal oscillator of a cantilever type to hold a crystal piece 5 by its one short side, comprising: through terminals 2b and 2c of AgPd on wall faces of open holes formed at corners of a rectangle ceramic substrate 1; connection terminals 2a1, 2a2, and 2a3 connected to the through terminals 2c, and metallic electrodes of support electrode lower layer parts 3a forming layers under support electrodes 3b that are formed from AgPd on a surface of the substrate 1, in which especially the connection terminal 2a2 is formed on the center side of the substrate 1 so that the connection terminal 2a2 is hidden behind the crystal piece 5, the support electrodes 3b formed from Ag that retain the crystal piece 5 on the support electrode lower layer parts 3a; and a cover 6 mounted on an insulator film 10 formed inside a circumference of the substrate 1 for hermetically sealing. There is also provided a method for manufacturing the oscillator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
