Abstract
A piezoelectric resonator (100) includes a piezoelectric resonating element (4), a lead frame (7), a base (8) and a common electrode plate (9). The lead frame includes common terminals (77, 722 and 791) connectable with two input and output electrodes (42 and 43) of the piezoelectric resonating element, first terminals (73, 731 and 76) electrically connectable with one of the two electrodes or the input electrode (42) of the piezoelectric resonating element, second terminals (75, 751, 78 and 723) electrically connectable with the other of the two electrodes or the output electrode (43) of the piezoelectric resonating element, and a connection member (79) for electrical connection of the common terminals with either one of the first and second terminals. When the connection member is disconnected from the first and second terminals, it becomes possible to structure a piezoelectric resonator with a plurality of piezoelectric resonating elements. Furthermore, when the connection member is detached from either of the first and second terminals, it becomes possible to structure a piezoelectric resonator with a single piezoelectric resonating element.
