a receiver on which the first ultrasonic wave is incident, the receiver being configured to output a signal corresponding to the incident first ultrasonic wave; and
a receiving-side waveguide located between the receiver and an inspection position,
the inspection position being between the transmitter and the receiver,
the first ultrasonic wave passing through the receiving-side waveguide,
an inspection object passing through the inspection position along a second direction crossing a first direction,
the first direction being from the transmitter toward the receiver,
the receiving-side waveguide including at least one of a first structure or a second structure,
in the first structure:
the receiving-side waveguide includes a tubular member and an inner member;
the inner member is located inside the tubular member; and
at least a portion of the inner member includes at least one of a mesh structure, a porous structure, or a surface unevenness structure,

in the second structure:
the receiving-side waveguide includes a tubular member; and
at least a portion of the tubular member includes at least one of a mesh structure, a porous structure, or a surface unevenness structure.
