Abstract
A magnetic marker set includes: a magnetic marker including a first rod and a second rod each formed of a stick-shaped ferromagnetic substance, and a stick-shaped third rod; and a needle with a hole in a longitudinal direction thereof. The magnetic marker includes a first connecting portion at which one longitudinal end of the first rod and one longitudinal end of the second rod are rotatably connected, and a second connecting portion at which other longitudinal end of the second rod and one longitudinal end of the third rod are rotatably connected. The magnetic marker is inserted into the hole and has been magnetized such that an orientation of a magnetic field reverses at the first connecting portion. The magnetic marker set includes a draw-in mechanism that brings other longitudinal end of the first rod and other longitudinal end of the third rod into contact with each other.
