Abstract
【解決手段】インサート成形体1は、熱可塑性樹脂成形体2と、インサート成形により成形体2と一体に成形される熱可塑性樹脂フィルム状体4とからなる。フィルム状体4は、インサート成形時に、その二次収縮率が成形体2の熱可塑性樹脂の収縮率以上となる温度に加熱されている。インサート成形体1の製造方法は、雌金型12の凹部14に熱可塑性樹脂フィルム状体4を配置し、フィルム状体4の一方の面上に成形体2を形成可能な形状のキャビティ16を形成し、フィルム状体4がキャビティ16内で、その二次収縮率が成形体2を形成する熱可塑性樹脂の収縮率以上となる温度に加熱されるようにして、該熱可塑性樹脂を射出成形する。
