Claim:
1. An ultrasound transducer comprising: at least one piezoelectric element; an electrode formed on a surface of the piezoelectric element; at least one conductive wire including a distal end that is in contact with the electrode; a metal film formed by an electroplating method, the metal film coating at least the distal end of the wire and the electrode that are in contact with each other such that no tension is applied to the wire, the metal film electrically connecting the electrode and the wire, an upper limit of a thickness of the metal film being not greater than one tenth a wavelength, in a material forming the metal film, of ultrasound having a highest frequency to be transmitted and received by the piezoelectric element; and a backing material charged in peripheries of the electrode and the metal film.
