To identify color of a part made of a preform and a part made of another resin, in a method of integrally molding the preform made of a resin and another resin by heating them in a mold by electromagnetic waves.SOLUTION: A resin molding method of integrally molding a first resin and a second resin by heating them in a mold Fm includes: arranging the first resin and a preform 12 that constitutes the second resin and is colored in advance with a color different from the color exhibited by the first resin in a cavity Cv of the mold Fm; melting the first resin and the preform 12 by radiating electromagnetic waves toward the cavity Cv; and giving an inverted cavity shape to the molten first resin and the molten preform 12 by decompressing the cavity Cv.SELECTED DRAWING: Figure 1 【課題】樹脂からなるプリフォームと他の樹脂とを成形型の中で電磁波によって加熱することでこれらを一体に成形する方法において、プリフォームからなる部分と他の樹脂からなる部分とを色分けする。【解決手段】第１樹脂と第２樹脂とを成形型Ｆｍの中で加熱することでこれらを一体に成形する樹脂成形方法であって、第１樹脂と、第２樹脂を構成するとともに第１樹脂の呈する色とは異なる色で予め着色されたプリフォーム１２とを成形型ＦｍのキャビティＣｖの中に配置し、キャビティＣｖに向けて電磁波で照射することで第１樹脂とプリフォーム１２とを溶融し、キャビティＣｖを減圧することで、溶融した第１樹脂と溶融したプリフォーム１２とに対してキャビティの形状が反転した形状を与える、樹脂成形方法。【選択図】図１
