<p>PROBLEM TO BE SOLVED: To provide an ultrasonic sensor device used as an ultrasonic transmission element and an ultrasonic reception element in which a distance unable to be measured with a reverberation signal is lessened, and an electronic apparatus having the ultrasonic sensor device.SOLUTION: There is provided an ultrasonic sensor device in which an ultrasonic element 1 transmitting an ultrasonic wave and receiving a reflected ultrasonic wave is stored in a case member, an ultrasonic transmission and reception hole 13a is provided in the case member, and the ultrasonic transmission and reception hole 13a is separated from the ultrasonic element 1 so that the reflected ultrasonic wave entered from the ultrasonic transmission and reception hole 13a does not reach the ultrasonic element 1 while a reverberation signal after stopping of the transmission of the ultrasonic wave is generated.</p> |
