Zusammenfassung:	To provide a vehicle cushion pad and a vehicle seat cushion that can reduce discomfort due to vibration during traveling of a vehicle and can obtain a good sitting comfort.SOLUTION: In a vehicle cushion pad 31 made of polyurethane foam which is placed on an upper surface of a cushion body 21, the polyurethane foam comprises a polyurethane foam composition containing a polyol, isocyanate, catalyst, foaming agent, and additive. The additive is a dicarboxylic acid ester compound having a weight average molecular weight of 500 to 5000. The air permeability of polyurethane foam according to JIS K 6400-7:2012 is 6.0 cc/cm2/s or more.SELECTED DRAWING: Figure 1 【課題】車両走行時の振動による不快感を低減させることができ、良好な座り心地が得られる車両用クッションパッドと車両用シートクッションの提供を目的とする。【解決手段】クッション本体２１の上面に載置されるポリウレタン発泡体からなる車両用クッションパッド３１において、ポリウレタン発泡体は、ポリオール、イソシアネート、触媒、発泡剤、添加剤を含むポリウレタン発泡体組成物からなり、添加剤は、重量平均分子量が５００〜５０００のジカルボン酸エステル化合物であり、ポリウレタン発泡体におけるＪＩＳＫ６４００−７：２０１２に準じた通気量が、６．０ｃｃ／ｃｍ２／ｓ以上である。【選択図】図１
