ABSTRACT:
An electronic component involving a two-terminal type piezo-electric device is disclosed. Bent portions are formed on a terminal to fix the device, and a supporting means projects from below a portion between the terminal and a lead to be bent inwardly, so that the connection between the piezo-electric device and the terminals can be firmly and perfectly done, that the supporting portion would be simple to manufacture, and that the flow-down of the solder can be prevented, thereby upgrading the reliability of the component, and improving the aesthetic appearance of the product. The electronic component includes a part 110 having a piezo-electric device 111 and having electrodes 112a and 112b on both sides of the piezo-electric so as to be overlapped at the middle portion. A terminal part 120 has a terminal 123 for being connected to each electrode of the piezo-electric 111, and the terminal has bent portions 121 with a bending angle .alpha. around a center line s so as to surround each end of the piezo-electric 111. A lead part 130 has a lead 132 extending downward from the inner lower end of the terminal, and has a frame 133 extending downward from the lower end of the lead 132. A supporting part 140 has a supporting means 141 which extends downward integrally from the connecting portion between the terminal 123 and the lead 132, and which is bent with a bending angle .beta. to support the piezo-electric 111.
