Abstract:
1. An ultrasound sensor, comprising: an ultrasound oscillator which is expandable and contractible in a thickness direction thereof; and a casing which houses therein the ultrasound oscillator, an outer surface of an end portion of the casing fixedly contacting a mounting member, wherein: the ultrasound oscillator has at least one of a protrusion portion, a concave portion and an inclined portion, through which one of two end surfaces of the ultrasound oscillator fixedly contacts an inner surface of the end portion of the casing, the protrusion portion protruding outwards from a side surface of the ultrasound oscillator, the concave portion being recessed from the side surface, the inclined portion being arranged at the side surface and being inclined with respect to the thickness direction of the ultrasound oscillator, the two end surfaces of the ultrasound oscillator intersecting the thickness direction of the ultrasound oscillator, the side surface of the ultrasound oscillator being substantially parallel with the thickness direction.
