Abstract

A resin impregnation detection device configured to detect resin impregnation in a resin impregnation process for a coil insulation layer. The resin impregnation detection device can be inserted in a narrow portion, is capable of detecting impregnation with a liquid resin, and does not leave metal foreign materials other than an optical fiber in a product even after the resin impregnation. The resin impregnation detection device includes an optical fiber including an FBG sensor, and a coating resin, which coats the FBG sensor. The coating resin includes a resin to be softened by contact with a detection target resin. The FBG sensor is applied with a compressive strain caused by cure shrinkage of the coating resin or heat shrinkage thereof from a curing temperature to a normal temperature.
