PROBLEM TO BE SOLVED: To provide a resin molded product and a door module capable of suppressing both stress concentration at a boundary portion between a solid portion and a foamed portion and lowering of allowable stress.SOLUTION: A resin molded product formed of a foamed part 30 having a large number of voids and a solid part 31 not having many voids comprises a main body part 21 and a first fitting part 22 provided integrally with the main body part 21. The first fitting part 22 and a predetermined region around the first fitting part 22 in the main body part 21 are formed from the solid part 31 and a portion adjacent to the predetermined region in the main body part 21 is formed from the foamed part 30. In the solid part 31, a boundary part 33 with respect to the foamed part 30 is formed by a thick part 34 equal to a thickness T2 of the foamed part 30. In the solid part 31, a portion farther away from the foamed part 30 than the thick part 34 has a thin portion 32 that is thinner than the thickness T2 of the foamed part 30.SELECTED DRAWING: Figure 6

    【課題】ソリッド部と発泡部との境界部分に応力集中が生じること、及び許容応力の低下の両方を抑制できる樹脂成形品及びドアモジュールを提供する。【解決手段】多数の空隙を有する発泡部30と、多数の空隙を有していないソリッド部31とから形成された樹脂成形品は、本体部21と、本体部21と一体に設けられた第1取付部22とを有する。第1取付部22と、本体部21における第1取付部22の周囲の所定領域とは、ソリッド部31から形成され、本体部21において所定領域と隣り合う部分は、発泡部30から形成されている。ソリッド部31において発泡部30との境界部分33は、発泡部30の厚さT2と等しい厚肉部34で形成され、ソリッド部31において厚肉部34よりも発泡部30から離れた部分は、発泡部30の厚さT2よりも薄い薄肉部32を有する。【選択図】図6
