An ultrasonic probe includes an ultrasonic device performing transmission and reception of ultrasonic waves, and an accommodation case to which an acoustic lens of the ultrasonic device is exposed and in which the ultrasonic device is accommodated. The accommodation case is formed of at least a first accommodation member and a second accommodation member, each of the first accommodation member and the second accommodation member including a suction path which is communicable with an external suction source. The first accommodation member includes, as the suction path, a first groove extending in a first direction, and the second accommodation member includes, as the suction path, a second groove extending in a second direction. The first and the second accommodation members are disposed to overlap each other, and the first direction and the second direction intersect each other in a thickness direction of the first accommodation member or the second accommodation member.
