Abstract
A foamed molding having a fastener comprises: a foamed body (41), pile threads (42) each having a leading end protruding from the front side of the first foamed body and a rear end exposing from the back side of the first foamed body, and a foamed body (60) formed on the back side of the foamed body (41). The pile threads (41) each have an extended portion (43) for locking at the leading end thereof. A part of stock solution for forming the foamed body (60) is impregnated from the back side of the foamed body (41) to thereby form an impregnated layer (61) between the foamed body (41) and the foamed body (60), the impregnated layer (61) functioning to secure the rear ends of the pile threads (42). The foamed molding having a fastener can follow a contraction phenomenon produced in the foaming process of foam resin when an impregnated type foamed molding is formed on the back side of the face-like fastener.
