Claims

[Scope of utility model registration request]

In a core metal holder for forming a microcoil, which winds a wire using a core metal and bends both ends, it is installed on the end face of the stepped part where the diameter decreases at the tip, and the coil wire is held between the core metal and the core metal holder. a protrusion to be passed through; a notch provided in the longitudinal direction from the tip of the stepped portion and into which the lead wire portion of the coil end is bent and abuts; and a shaft communicating with a guide hole of the core metal drilled in the stepped portion. A central hole that penetrates in the axial direction, a hole that is arranged concentrically in a part of the central hole and through which the core metal is passed through the center in the axial direction, and a hole that uniformly decreases in diameter by a force perpendicular to the axial direction. 1. A core metal holder for forming a microcoil, comprising a split ring having two slits along its entire length, and a threaded hole on the side for tightening the split ring with a screw from a direction perpendicular to the axis.
