    Abstract: An ultrasonic wave measuring device includes: an ultrasonic wave transmission and reception unit configured to perform ultrasonic wave transmission and reception processing of transmitting ultrasonic waves to an object and receiving the ultrasonic waves reflected by the object, and to output reception signals based on reception of the ultrasonic waves; a zero-crossing detection unit configured to detect a plurality of zero-crossings corresponding to the reception signals whose signal voltages are equal to or higher than a predetermined threshold; and a reception setting unit configured to set a reception zero-crossing used as a reception timing based on the plurality of zero-crossings. The reception setting unit is configured to calculate a difference between a zero-crossing detection time from a transmission timing of the ultrasonic waves to a time at which zero-crossing is detected and a predetermined reference time for each of the plurality of the zero-crossings, and to set one of the zero-crossings at which the difference is minimum among the plurality of zero-crossings as the reception zero-crossing.

    Abstract: An ultrasonic sensor includes a transmission unit that is disposed on a first axis which is inclined with respect to a normal line of a surface of an object, a reception unit that is provided on a side opposite to the transmission unit of the object, on the first axis, and a transmission control unit that controls drive of the transmission unit. The transmission unit includes a plurality of transmission elements that transmit ultrasonic waves, and the plurality of transmission elements are arranged in a first direction that intersects the first axis in a plane including the normal line and the first axis. The transmission control unit delay-drives the plurality of transmission elements to align a direction of the ultrasonic wave that is transmitted from the transmission unit with the first axis.
