A magnet composite having excellent magnetic properties, spontaneous disintegration, and a residue having a very small impact on the environment after natural disintegration is produced. A naturally disintegrating resin and a magnetic material are mixed, molded, and then magnetized to produce a magnet composite. The naturally disintegrating resin is a biodegradable resin, and the biodegradable resin is a polyester resin. One of lithium, sodium, magnesium, aluminum, silicon, potassium, calcium, titanium, germanium, yttrium, and zirconium is added to the magnetic substance. [Selection figure] None |
