To reduce quality deficiencies in resin moldings.SOLUTION: A resin molding device has: a first molding die 2 having a pot 21 to house a resin material J wrapped with a cover 7; and a second molding die 3 that faces the first molding die 2 and has a cull part 32 at a portion facing the pot 21. At least one of the first molding die 2 and the second molding die 3 is provided with a cavity 31, and the cavity 31 is provided with runner parts 33 connecting the cull part 32. The inner surface of the cull part 32 has, at positions corresponding to the runner parts 33, recesses 3M or projections 3T.SELECTED DRAWING: Figure 4 【課題】樹脂成形品の品質不良を低減する。【解決手段】被覆体７が巻かれた樹脂材料Ｊが収容されるポット２１が形成された第１の成形型２と、第１の成形型２に対向して設けられ、ポット２１に対向する部分にカル部３２が形成された第２の成形型３とを備え、第１の成形型２又は第２の成形型３の少なくとも一方に、キャビティ３１が形成されるとともに、キャビティ３１にカル部３２を接続するランナ部３３が形成されており、カル部３２の内面においてランナ部３３に対応する位置に凹部３Ｍ又は凸部３Ｔが形成されている。【選択図】図４
