An ultrasound transducer unit includes: an ultrasound element; a substrate; a signal transmission cable; a cylindrical metal shield member that has a large-diameter portion, a small-diameter portion, and a step portion, in which the large-diameter portion covers an outer circumference of the substrate; ground wiring that electrically connects the substrate and an outer circumferential face of the metal shield member; and an opening portion formed in the step portion or the small-diameter portion. The ground wiring is extended to outside the metal shield member from inside the large-diameter portion through the opening portion, and is electrically connected to an outer circumferential face of the small-diameter portion to thereby electrically connect the substrate and the outer circumferential face of the metal shield member.
