An object of the present invention is to provide a magnetic encoder in which a stainless steel plate and a rubber magnet are joined, which are excellent in water resistance, salt water resistance and the like. An undercoat adhesive containing a copolymerized oligomer of an amino group-containing alkoxysilane and a vinyl group-containing alkoxysilane (and an organic phosphorus compound) on a stainless steel sheet, a topcoat adhesive containing a phenol resin and an epoxy resin, and A magnetic encoder in which rubber magnets whose base polymer is NBR or ethylene-methyl acrylate copolymer rubber are sequentially laminated. |
