PURPOSE: To produce a good product efficiently by setting a hook blank body inside a cavity in the state of inserting it into a hook holder, by packing a resin inside a metal die and by bending the hook blank body at the prescribed angle after integrating the hood holder and cuttlefish hook.

CONSTITUTION: A hook blank body 4 is held by inserting it into a tubular hook holder 3 and set to the cavity 2 of bisected metal die 1, 1'. The fitting hole 6 of several pieces of hook blank bodies 4 is provided on the holder 3 and the hook bottom part 8 of the blank body 4 in L shape is fitted thereto. The hook holder 3 and hook main body A are contacted with welding by packing synthetic resin inside the metal die 1, 1', then. The forming item is taken out of metal die 1, 1' and the hook blank body 4 is bent adequately. A good product can thus be mass-produced, in bulk.
