<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic sensor unit capable of presenting maximum performance during both ultrasonic wave transmission and reception. <P>SOLUTION: The present invention relates to an ultrasonic sensor unit 10, comprising an ultrasonic transmission sensor array 50 including a plurality of ultrasonic transmission sensors 52 for transmitting ultrasonic waves and an ultrasonic reception sensor array 51 including a plurality of ultrasonic reception sensors 53 for receiving ultrasonic waves. The ultrasonic transmission sensor array 50 and the ultrasonic reception sensor array 51 are pasted in such a way that the ultrasonic transmission sensors 52 and the ultrasonic reception sensors 53 are not overlapped in plane view and in either the ultrasonic transmission sensor array 50 or the ultrasonic reception sensor array 51, a through-hole 11b is formed for exposing the ultrasonic sensors 53 in the other array 51, for example. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
