Abstract

PURPOSE:To provide an ultrasonic probe holder improved to prevent failure and flawing of the acoustic lens surface of an ultrasonic probe. CONSTITUTION:The base 1 of a housing space is formed to an approximately V shape in section and the gaps between opposite side faces 2 and 3 of the housing space are made wider than the thickness-component of cases CK, CL of the ultrasonic probe B in such a manner that the acoustic lens surface of the ultrasonic probe P does not come into contact with the base 1 of the housing space even if the case part on the outer side of the acoustic lens surface comes into contact with the base 1. As a result, at least the central part of the acoustic lens surface does not come into contact with the base of the housing space and, therefore, impact is not applied on the acoustic lens surface L and the failure and flawing of the acoustic lens surface are substantially prevented.
