1. A magnetic structural body comprising:
core-shell structure particles, each including a core section and a shell section covering the surface of the core section,
wherein the core section is made of an alloy containing a first metal and a second metal,
the shell section is made of an alloy which contains the first metal and the second metal and which has a first metal-to-second metal content ratio different from that of the core section,
the first metal is a magnetic metal and has a standard redox potential higher than that of the second metal, and
the neighboring core-shell structure particles are linearly linked to each other.
