。 It has a light receiving section that receives light from a light projecting section having a light source that emits light radially through a sheet-like object, and the sheet-like object is detected based on a signal from a light receiving element provided in the light receiving section. In a moisture measuring device for a sheet-like object that measures moisture content, most of the light source is surrounded by one end surface of a plurality of bundled optical fibers, and the other end of the bundled plurality of optical fibers is formed into a disk shape. A magic mirror is arranged so that the transmitting surface is in contact with the disc-shaped surface and the reflecting surface faces the light receiving element side, and the magic mirror is arranged so that the center of the magic mirror is located at the center of the entrance window of the light receiving part. A moisture measuring device for sheet-like objects, characterized by:
