Abstract
Provided is a winding apparatus that is provided with a splitter that splits radiant light from a light source unit into measurement light applied to a side face part of a first sheet and a second sheet and reference light applied to a reference surface, an interference detector that detects interference light formed by interference between the reference light reflected by the reference surface and the measurement light reflected by the side face part, a position detector that detects the position of the first sheet and the position of the second sheet on the basis of the detected interference light, and a decision processor that decides the quality of the wound body on the basis of the detected positions of the first sheet and the second sheet.
