Zusammenfassung:	PURPOSE: A material sensing device is provided to accurately confirm a position of a material according to whether a fluid reaches a sensor unit or not. CONSTITUTION: A material sensing device comprises a nozzle unit(10) and a sensor unit(20). The nozzle unit sprays a fluid between rollers moving the material. The sensor unit senses the material on a spraying passage of the fluid according to whether the fluid being sprayed from the nozzle unit reaches the sensor unit. The sensor unit comprises a measuring tube unit, a moving ball unit, and a sensing unit. The measuring tube unit is placed in upward of the nozzle unit and the fluid flows into the measuring tube unit. The moving ball unit is embedded in the measuring tube unit and moves up and down by the fluid. The sensing unit senses a position of the moving ball unit.
