Zusammenfassung:	To provide a method of manufacturing an in-mold label container capable of suppressing appearance defects and suppressing molding defects.SOLUTION: A method of manufacturing an in-mold label container 10 has a step of preparing a mold 20 having a core 21 and a mold 22 with a cavity, a step of mounting a label 4 in which a gate hole 7a through which an injection resin 8 passes is formed in the mold 20, and a step of injecting the injection resin 8 to the label 4 mounted in the mold 20. At least one of the core 21 of the mold 20 and the mold 22 with a cavity is surface-treated at a position across at least one of a peripheral edge 4a of the label 4 and the gate hole 7a when the label 4 is mounted.SELECTED DRAWING: Figure 7A 【課題】外観不良を抑制するとともに、成形不良を抑制することができるインモールドラベル容器の製造方法を提供する。【解決手段】インモールドラベル容器１０の製造方法は、コア２１とキャビティ付金型２２とを有する金型２０を準備する工程と、金型２０内に、射出樹脂８が通過するゲート穴７ａが形成されたラベル４を装着する工程と、金型２０内に装着されたラベル４に、射出樹脂８を射出する工程とを備えている。金型２０のコア２１およびキャビティ付金型２２のうち少なくとも一方には、ラベル４が装着された状態においてラベル４の周縁４ａおよびゲート穴７ａのうち少なくとも一方を跨ぐ位置に、表面処理が施されている。【選択図】図７Ａ
