1. An ultrasonic inspection system that causes an ultrasound beam to enter an object through a gas for inspection of the object, the device comprising:
a transmission probe emitting the ultrasound beam;
a reception probe mounted on an opposite side of the object from the transmission probe; and
a distance adjuster that adjusts an eccentric distance between a transmission sound axis of the transmission probe and a reception sound axis of the reception probe to a distance greater than zero, wherein
the transmission probe and the reception probe perform scanning while keeping the eccentric distance in an x-axis direction or a y-axis direction on condition that an x-y plane is approximately parallel to a bottom of the object, and
the transmission probe is mounted such that the transmission sound axis is perpendicular to the x-y plane.
