The mold is composed of bonded water-insoluble particles, the mold being characterized in having a molding layer and a support layer. The molding layer consists of first water insoluble particles, having an average size of 0.2 - 1.0 mm bonded to form a layer having a thickness 1 - 20 times the average size of the first particles. The support layer positioned on the inner surface of the molding layer, on which the fiber bodies are not formed, consists of second water-insoluble particles, having an average size of 1.0 - 10.0 mm, bonded to form a layer having a thickness of at least the average size of the second particles. The pulp mold has advantages in that it hardly suffers from clogging, it produces fiber bodies each having a smooth surface, it is free from damage caused by repeated use, and it produces fiber bodies in a short period of time.
