Abstract:
1. An ultrasound probe comprising: an ultrasound transmission/reception portion having an ultrasound transmission/reception surface for transmitting and receiving ultrasound; a cable having a distal end electrically connected to the ultrasound transmission/reception portion; a housing configured to hold the ultrasound transmission/reception portion such that the ultrasound transmission/reception surface is exposed; a hole portion provided to the housing and configured to lead out the cable from inside of the housing; an insulation pipe through which the cable is inserted, the insulation pipe having a distal end side fixed to the hole portion in a state of contacting an inner circumference of the hole portion, and a proximal end side exposed outside the housing; an insulation tube configured to cover an outer circumference of an exposed region of the insulation pipe which is exposed from the hole portion and an outer circumference of the cable led out from a proximal end of the insulation pipe; an adhesive disposing area located from a distal end of the insulation tube for a predetermined distance between the outer circumference of the exposed region of the insulation pipe and an inner circumference of a distal end side region of the insulation tube covering the outer circumference of the exposed region; an adhesive permeation preventing area located between the outer circumference of the exposed region of the insulation pipe and the inner circumference of the distal end side region of the insulation tube covering the outer circumference of the exposed region, at least a part of the adhesive permeation preventing area being located on a proximal end side with respect to the adhesive disposing area; an adhesive located in the adhesive disposing area and configured to adhere the insulation pipe and the insulation tube to each other; and a liquid dripping prevention portion disposed in the adhesive permeation preventing area between the outer circumference of the exposed region of the insulation pipe and the inner circumference of the distal end side region of the insulation tube, the liquid dripping prevention portion being configured to prevent the adhesive from flowing out from the proximal end of the insulation pipe and contacting the cable.
