Abstract: It is an object to provide a reel capable of expecting strength and dimensional accuracy almost equivalent to those of a metal reel, preventing product failures from being caused by the generation of metal powder, exchanging only a damaged part even in the case in which the part of a member for protecting the reel main body is damaged, being manufactured at a low cost by the miniaturization of a metal mold structure, and preventing a carrier tape and a wiring pattern from being damaged or broken as much as possible.
