Claim Text:
1. An ultrasonic transducer element chip comprising: a substrate including a substrate surface and a plurality of opening portions arranged in an array pattern, each of the opening portions extending from the substrate surface in a first direction along a perpendicular direction that is perpendicular to the substrate surface; a plurality of ultrasonic transducer elements arranged, relative to the substrate surface, in a second direction along the perpendicular direction, the second direction being opposite the first direction, the ultrasonic transducer elements being arranged so as to correspond to, in the perpendicular direction, the opening portions, respectively; a wiring part connected to the ultrasonic transducer elements; and an additional wiring part disposed in a peripheral region between an outline of the array pattern of the openings and an outer edge of the substrate such that the additional wire part and the ultrasonic transducer elements do not overlap with respect to each other in the perpendicular direction, the additional wiring part being electrically insulated from the wiring part, and the additional wiring part being longer than a shortest distance between the outline of the array pattern and the outer edge of the substrate as viewed in the perpendicular direction.
