PROBLEM TO BE SOLVED: To put an electrode of a piezoelectric element on a circuit device with one-touch operation. SOLUTION: End surfaces 4a and 5a of attachment bases 4 and 5 are inclined from an axis line of a tubular body 1, and rectangular piezoelectric elements 2 and 3 are fixed to the end surfaces 4a and 5a via an adhesive. Positive and negative electrodes 6 and 7 provided on front and rear faces of the piezoelectric elements 2 and 3 are formed to protrude sideward of the attachment bases 4 and 5 together with part of the piezoelectric elements 2 and 3. When the tubular body 1 is mounted on a circuit box, the positive and negative electrodes 6 and 7 of the piezoelectric elements 2 and 3 are inserted between pinching pieces of a contact member, and thereby the positive and negative electrodes 6 and 7 are connected with an electric circuit part in the circuit box.
