PROBLEM TO BE SOLVED: To provide an insert molding capable of surely preventing positional deviation of a film body, and a production method of the same.SOLUTION: A production method of an insert molding 1 comprising a film body 11 on which a pattern is formed, and a resin molded body 31 integrally provided on one surface side of the film body 11, comprises: a layer formation step A1 for forming an overcoat layer 21 on the other surface side of the film body 11; a three-dimensional molding step B1 for three-dimensionally molding the film body 11; a fitting step C1 for setting the film body 11 in a mold 15 so that the overcoat layer 21 and a surface 15a of the heated mold 15 are brought into close contact with each other; a molding step D1 for forming the resin molded body 31 by injecting a synthetic resin in the mold 15 after mold clamping; and a take-out step E1 for taking out the molding with which the film body 11 is integrated from the mold 15, while lowering temperature of the resin molded body 31, after mold opening. A friction coefficient of the overcoat layer 21 during high temperature is higher than that during low temperature.SELECTED DRAWING: Figure 2 【課題】フィルム体の位置ズレが確実に防止されたインサート成形品およびその製造方法を提供する。【解決手段】パターンが形成されたフィルム体１１と、フィルム体１１の一面側に一体となって設けられた樹脂成形体３１と、を備えたインサート成形品１の製造方法であって、フィルム体１１の他面側にオーバーコート層２１を設ける層形成工程Ａ１と、フィルム体１１を立体的に成形する立体成形工程Ｂ１と、オーバーコート層２１と加熱された金型１５の表面１５ａとが密着するように金型１５内にフィルム体１１をセットする装着工程Ｃ１と、型閉め後、金型１５内に合成樹脂を注入し樹脂成形体３１を形成する成形工程Ｄ１と、型開き後、樹脂成形体３１の温度を下げながらフィルム体１１が一体となった成形体を金型１５から取り外す取り出し工程Ｅ１と、を有し、オーバーコート層２１が低温時の摩擦係数よりも高温時の摩擦係数が高くなっている。【選択図】図２
