| 摘要 |
An electronic component of an embodiment of the present invention comprises a first piezoelectric thin film resonator and a second piezoelectric thin film resonator. The first piezoelectric thin film resonator and second piezoelectric thin film resonator are a piezoelectric thin film resonator that has a structure in which a piezoelectric thin film is interposed between a lower electrode and an upper electrode, that is constituted in an area where the lower electrode, piezoelectric thin film, and upper electrode overlap each other, and that obtains a signal with a predetermined resonance frequency by bulk waves propagating inside the piezoelectric thin film. The interval between a part of a periphery of the first piezoelectric thin film resonator and a part of a periphery of the second piezoelectric thin film resonator that face each other is not constant.
