ULTRASONIC INSPECTION DEVICE

To reduce a diffracted wave reaching a reception part regardless of a mode of conveyance of an analyte between a transmission part and the reception part in an ultrasonic inspection device.SOLUTION: An ultrasonic inspection device 1 includes: a transmission part 10 for transmitting an ultrasonic wave W; a reception part 20 which is positioned at an interval relative to the transmission part 10 and receives the ultrasonic wave W; and an attenuation member 30 which attenuates the ultrasonic wave W. The attenuation member 30 is located between the transmission part 10 and the reception part 20, and has a contact part 31 which is in contact with an edge part 103 of an analyte 100 passing through the transmission part 10 and the reception part 20. The contact part 31 is formed so as to wrap around the edge part 103 of the analyte 100 passing between the transmission part 10 and the reception part 20 at an arbitrary position in an arrangement direction of the transmission part 10 and the reception part 20.SELECTED DRAWING: Figure 1 【課題】超音波検査装置において、送信部と受信部との間における被検体の搬送の態様に関わらず、受信部に到達する回折波を低減できるようにする。【解決手段】超音波検査装置１は、超音波Ｗを送信する送信部１０と、送信部１０に対して間隔をあけて位置し、超音波Ｗを受信する受信部２０と、超音波Ｗを減衰させる減衰部材３０と、を備える。減衰部材３０は、送信部１０と受信部２０との間に位置し、送信部１０と受信部２０との間を通過する被検体１００の縁部１０３に接触する接触部３１を有する。接触部３１は、送信部１０及び受信部２０の配列方向の任意の位置において送信部１０と受信部２０との間を通る被検体１００の縁部１０３を包み込むように形成されている。【選択図】図１
