<p><P>PROBLEM TO BE SOLVED: To provide a highly reliable impact sensor by improving adhesive strength of connecting electrodes onto support members. <P>SOLUTION: This impact sensor is equipped with the connecting electrodes 17a, 17b provided on the inner surface so as to be exposed to the ends of a pair of support members 15a, 15b having recessed parts on the inside parts, a rectangular piezoelectric vibrator 14 having an internal electrode 12 and surface electrodes 13a, 13b 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. Irregularities are formed on the recessed part surfaces of the support members 15a, 15b. <P>COPYRIGHT: (C)2004,JPO</p> |
