ULTRASONIC PROBE

摘要

There is provided an ultrasonic probe containing an ultrasonic element section and an ultrasonic wave propagation medium in a containing section formed by coupling a window and a frame. It is possible to suppress generation of a gap between the window and the frame when the temperature varies. The ultrasonic probe comprises an ultrasonic element section (1) for transmitting/receiving ultrasonic wave, a frame (4) for supporting the ultrasonic element section (1), a window (5) coupled with the frame (4) to surround the ultrasonic element section (1), and an ultrasonic wave propagation medium filling a space surrounded by the frame (4) and the window (5). The window (5) includes a resin part (5b) transmitting an ultrasonic wave, and a metal part (5a) having one part buried in the resin part (5b) and the other part exposed outside of the resin part (5b). Coupling between the window (5) and the frame (4) is realized by coupling of the part of the metal part (5a) exposed outside of the resin part (5b) with the frame (4).
