1. An inspection method, comprising:
causing a probe to transmit an ultrasonic wave toward a weld portion and to receive a reflected wave, the probe including a plurality of ultrasonic sensors arranged in a first direction, the ultrasonic wave being transmitted along a second direction crossing the first direction;
adjusting an angle of the probe around a third direction based on the reflected wave, the third direction being perpendicular to the first direction and crossing the second direction; and
inspecting the weld portion after adjusting the angle of the probe.
