Provided is a filler connection part inspection method by which the connection state of both end surfaces (531, 532) of a belt-shaped filler (53) that has been affixed annularly along the outer periphery of a bead core (52) is inspected. The filler connection part inspection method includes: a step for scanning, at the side surfaces of the filler (53), sections of the vicinity of the both end surfaces (531, 532) by using optical sensors (33A, 33B) over a prescribed scanning range along the connection direction of the filler (53), and for acquiring data pertaining to the distance between the optical sensors (33A, 33B) and the side surfaces of the filler (53); a step for repeating the data acquisition step while the positions of the optical sensors (33A, 33B) are changed along the radial direction of the filler (53); and a step for comparing the acquired data with preset reference data. |
