Ultrasonic transducer element chip, probe, electronic instrument, and ultrasonic diagnostic device

摘要

An ultrasonic transducer element chip includes a substrate, a plurality of ultrasonic transducer elements, a reinforcing member and a ventilation passage. The substrate defines a plurality of openings arranged in an array pattern. The ultrasonic transducer elements are respectively disposed at the openings on a first surface of the substrate. The reinforcing member is fixed on a second surface of the substrate opposite to the first surface of the substrate to reinforce the substrate. Through the ventilation passage, internal spaces of the openings and an external space of the substrate are in communication with each other.
