Piezoelectric transformer having a recess to surely maintain a position of an elastic member press-fitted between an electrode and a terminal

摘要

A piezoelectric transformer includes: a piezoelectric transducer on whose outer surface an electrode is formed; a case housing the piezoelectric transducer; a terminal disposed to face the electrode; an elastic member in contact with both the electrode and the terminal in the case and having conductivity to bring the electrode and the terminal into mutual continuity; and a folder formed in the case and fixedly holding the elastic member to press-fit the elastic member between the electrode and the terminal.
