The proximity sensor (6) is, for example, a horizontally long rod-shaped eddy current sensor, and has a positioning attachment (4a).
(4b) is penetrated and fixed to one lower part of (4b). When the pair of positioning attachments (4a) and (4b) move close to each other and push the glass plate (1) from both sides, the positioning attachment without the proximity sensor (6) is arranged at an interval D proportional to the plate thickness of the glass plate (1). (4a) and the tip of the proximity sensor (6) face each other. An eddy current proportional to the facing distance D is generated in the proximity sensor (6), and the plate thickness of the glass plate (1) is inspected by detecting the eddy current. The glass plate thickness inspection by the proximity sensor (6) is performed simultaneously with the positioning of the glass plate (1). Further, this plate thickness inspection is a test performed indirectly on the positioned glass plate (1), but there is a proportional relationship between the plate thickness of the glass plate (1) and the detection signal of the proximity sensor (6). Since it is stable, its inspection accuracy is high.
