Abstract
A piezoelectric transformer having a structure where an electrode on a side of a transformer element and a lead terminal made of a leaf spring on a side of a package are brought into pressural contact with each other by an elastic spring performance of the lead terminal. An angle of inclination is given to a terminal portion of the lead terminal in respect of a base portion, whereby the terminal portion of the lead terminal is opened in a direction of extending the base portion, when the base portion is bent, with a side wall of a case being a fulcrum for the bending, by receiving a static pressing force from a transformer element on the terminal portion. An angle of rotation caused at the terminal portion by bending the base portion is counteracted by this angle of inclination, by which the terminal portion and the electrode of the transformer element are always kept in parallel with each other.
