Abstract

An ultrasonic transducer device (17) includes a base (21), a plurality of piezoelectric elements (25), a conductive body (28, 31) and an insulating film. The base (21) has a plurality of vibrating film portions (24) arranged in an array (22) pattern. The piezoelectric elements (25) are respectively disposed on the vibrating film portions (24). The conductive body (28, 31) is disposed on the base (21), and arranged inside and outside of an area corresponding to each of the vibrating film portions (24) in a plan view as viewed along a thickness direction of the base (21). The insulating film is disposed on the conductive body (28, 31) only at outside of the area corresponding to each of the vibrating film portions (24) in the plan view.
