Abstract
A welding portion inspection device includes a device body, a probe, a sound propagation medium, an elastic support mechanism configured to allow the probe and the sound propagation medium to be elastically supported to the device body, and a guide member formed of a material higher in hardness than a metal plate. The guide member is disposed such that a first part is positioned on a side of the sound propagation medium and second parts protrude beyond a tip surface of the sound propagation medium. The probe is configured to oscillate a ultrasonic wave such that the ultrasonic wave is emitted to a welding portion of the metal plate through the sound propagation medium and perform inspection of the welding portion based on a detected reflected wave of the ultrasonic wave in a state where the tip surface of the sound propagation medium faces the welding portion.
