The mold-in fastening member, that can be molded into a resin article, of the present invention comprises (a) a substrate having a front surface and a back surface (b) a plurality of engaging elements provided on the front surface (c) a plurality of anchoring elements provided on the back surface, the anchoring elements being embedded into the resin article to fix the mold-in fastening member thereto (d) a ferrite-containing layer formed on the front surface (e) marginal portions continuously extending along respective lengthwise edges of the substrate and (f) grooves formed on the substrate, which extend along the respective marginal portions to render the marginal portions easily bending relative to the substrate. The fastening member is easily placed in position on shoulders of a recess formed on a mold and protects the engaging elements from being buried or contaminated by a foaming resin because the ingress of the foaming resin into the recess is effectively prevented due to the close contact of the marginal portions with the shoulders. The fastening member of the present invention is small in size and improve the productivity, safety and working efficiency of the production of molded resin articles having mold-in fastening members.
