Abstract
A technique that provides: an ultrasonic transducer in which the accurate arrangement of piezoelectric elements and the electric conductive state between electrode layers are reserved; and an ultrasonic diagnosis apparatus and an ultrasonic flaw inspection apparatus which use the ultrasonic transducer is provided. According to the technique, a plurality of piezoelectric elements, each being a stacked body in which predetermined numbers of piezoelectric layersand electrode layersare alternately stacked and although this has both sides that are substantially flat along a stacking direction, side electrodesto connect the predetermined electrode layersare placed outside both of the sides, are arranged in a direction orthogonal to the stacking direction, wherein an interval holding memberhaving a predetermined thickness is put between the sides on which the side electrodesof the piezoelectric elementsadjacent to each other are formed.
