Provided is a device that transmits and receives an ultrasonic wave to and from an entire periphery of a specimen while preventing a movement of the specimen. An ultrasonic wave transmission and reception device includes: an oscillator array that is arrayed with an oscillator, the oscillator transmitting and receiving an ultrasonic wave; a fixing tool that is disposed between the oscillator array and the specimen and retains the specimen; and a drive mechanism that presses at least a part of the fixing tool against the specimen as to retain the specimen. An ultrasonic wave transmitted by the oscillator array passes through the fixing tool and irradiates on the specimen, and as for the oscillator array, the oscillator array and the fixing tool are disposed in a positional relationship such that the ultrasonic wave reflected by and/or passing through by the specimen and passing through the fixing tool is received.
