An ultrasonic probe is provided that makes it possible to increase the shock resistance of a board of an ultrasonic device unit. An ultrasonic probe includes a housing. The housing defines an opening and an accommodation space that is continuous with the opening. An ultrasonic device unit is disposed in the accommodation space. A board has on its first surface an ultrasonic transducer that faces the opening. A rigid body is in contact with a second surface of the board and the housing. The rigid body has higher stiffness than the board.
