Abstract: Each of all ultrasound transducers constituting an ultrasound transducer group of an ultrasound transmitting/receiving portion is connected to a circuit board via electrical wiring so that all the ultrasound transducers can transmit/receive ultrasound. Therefore, even if a second ultrasound transducer group which causes ultrasound to be reflected in a housing occurs due to a shape (inclination and an amount of projection), influence and the like of an outer circumferential portion of an opening portion of the housing, a first ultrasound transducer group capable of emitting ultrasound from the opening portion is appropriately secured.
