摘要： Provided are an in-mold foam molded article that can be formed with improved dimensional accuracy while warping is suppressed, a method for forming such an article, and a mold for use in forming such an article. The in-mold foam molded article 1 includes a foam body 2 including olefin-based resin pre-expanded beads; and an insert member 3 including an elongated connecting portion 6 and movement resisting portions 7 provided apart from one another in the connecting portion 6, the insert member 3 being subjected to insert molding upon in-mold foam molding using the olefin-based resin pre-expanded beads. A movement facilitating structure is provided to facilitate relative movement between the insert member 3 and the foam body 2 during shrinkage of the in-mold foam molded article 1 released from the mold, and has a dividing space 5 that is formed along a direction crossing the connecting portion 6 to divide the foam body 2 into two divided foam parts 4.
