PROBLEM TO BE SOLVED: To provide an impact sensor capable of ensuring connection between a connecting electrode and external electrodes. SOLUTION: This impact sensor is equipped with connecting electrodes 17a, 17b provided on the inner surfaces so as to be exposed to the ends of a pair of support members 15a, 15b having recessed parts inside, a rectangular piezoelectric vibrator 14 having electrodes 12, 13a, 13b inside and on both main faces having each one end interleaved by the support members 15a, 15b, a conductive member 16 provided so as to be sandwiched between the other end of the piezoelectric vibrator 14 and the opposite support members 15a, 15b, and external electrodes 18a, 18b provided on the end faces of the support members 15a, 15b. Corner parts constituting the recessed parts of the support members 15a, 15b have curved faces. COPYRIGHT: (C)2004,JPO
