Abstract
A molded surface fastener, in which many magnetic particles can be contained in a closer part with respect to a magnet of a molding die, and further a front surface and a rear surface can be easily identified, is provided. In the molded surface fastener of the invention, a magnetic region containing magnetic particles is formed on at least a part between right and left resin intrusion barrier portions, and a magnetic raised portion which is lower than engaging elements and contains the magnetic particles therein is disposed between the engaging elements adjacent in a length direction within the magnetic region.

A molded surface fastener made of synthetic resin which is integrated to a surface of a cushion body when foam molding of the cushion body, the molded surface fastener comprising:
- a flat plate-shaped base portion, right and left resin intrusion barrier portions standing along a length direction on an upper surface of the base portion, and a plurality of hook-shaped engaging elements disposed between the right and left resin intrusion barrier portions, in which a magnetic region containing magnetic particles in the synthetic resin is formed along the length direction in at least a part between the right and left resin intrusion barrier portions,
- wherein magnetic raised portions integrally formed with the base portion and rising from the upper surface of the base portion such that a height dimension in a vertical direction is lower than the engaging elements and containing the magnetic particles therein are disposed alternately between the engaging elements adjacent in the length direction within the magnetic region,
- the magnetic raised portions are formed on at least a position interposed by the adjacent engaging elements in the length direction.
