A piezoelectric switch is provided to simplify the structure of a switch and facilitate the fabricating process by including an electrode formed on one or both surfaces of a piezoelectric body, two metal pieces for transferring an electrical signal to a driving circuit, and a cap for fixing a piezoelectric device composed of the piezoelectric body and the electrode. A piezoelectric body(40) is prepared. A cap(20) fixes the piezoelectric body. Two electrodes(32,33) are formed on one surface of the piezoelectric body. Two metal pieces(51,52) output an electrical signal generated from the piezoelectric body to a driving circuit of a piezoelectric switch. Another electrode(31) is formed on the other surface of the piezoelectric body.
