An ultrasound probe comprising: an ultrasound transmission/reception portion having an ultrasound transmission/reception surface for transmitting and receiving ultrasound; and 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 outside of the housing; 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; characterized in that the ultrasound probe further comprises: an adhesive located at a distal end side area of the exposed region of the insulation pipe between the outer circumference of the exposed region and a distal end side region of the insulation tube covering the outer circumference of the exposed region, the adhesive being configured to adhere the insulation pipe and the insulation tube to each other; and a liquid dripping prevention portion (36m, 36t, 61, 62) disposed between the outer circumference of the exposed region of the insulation pipe and the distal end side region of the insulation tube at an area that is more proximal end side than the area where the adhesive is applied, the liquid dripping prevention portion (36m, 36t, 61, 62) being configured to prevent the adhesive from flowing out from the proximal end of the insulation pipe and contacting the cable. an ultrasound transmission/reception portion having an ultrasound transmission/reception surface for transmitting and receiving ultrasound; and 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 outside of the housing; 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; characterized in that the ultrasound probe further comprises: an adhesive located at a distal end side area of the exposed region of the insulation pipe between the outer circumference of the exposed region and a distal end side region of the insulation tube covering the outer circumference of the exposed region, the adhesive being configured to adhere the insulation pipe and the insulation tube to each other; and a liquid dripping prevention portion (36m, 36t, 61, 62) disposed between the outer circumference of the exposed region of the insulation pipe and the distal end side region of the insulation tube at an area that is more proximal end side than the area where the adhesive is applied, the liquid dripping prevention portion (36m, 36t, 61, 62) being configured to prevent the adhesive from flowing out from the proximal end of the insulation pipe and contacting the cable. an adhesive located at a distal end side area of the exposed region of the insulation pipe between the outer circumference of the exposed region and a distal end side region of the insulation tube covering the outer circumference of the exposed region, the adhesive being configured to adhere the insulation pipe and the insulation tube to each other; and a liquid dripping prevention portion (36m, 36t, 61, 62) disposed between the outer circumference of the exposed region of the insulation pipe and the distal end side region of the insulation tube at an area that is more proximal end side than the area where the adhesive is applied, the liquid dripping prevention portion (36m, 36t, 61, 62) being configured to prevent the adhesive from flowing out from the proximal end of the insulation pipe and contacting the cable.
