To provide a fiber reinforced composite material laminate capable of simplifying a manufacturing process and further good in surface property.SOLUTION: A fiber reinforced composite material laminate 10 has a core part 1 containing a foam resin and a thermosetting resin containing a carbon fiber, and a surface layer part 2 adhered to a surface of the core part 1. The foam resin of the core part 1 at a state that the core part 1 and the surface layer part 2 are not adhered has arithmetic average roughness Ra of 59 μm or less and maximum diameter of a cell of a surface of 0.6 mm or less.SELECTED DRAWING: Figure 1 【課題】製造工程を簡略化することができ、さらに表面性状も良好な繊維強化複合材料積層体の提供。【解決手段】繊維強化複合材料積層体１０は、発泡樹脂を含有する芯部１と、炭素繊維を含有する熱硬化性樹脂を有し、芯部１の表面に密着される表層部２とを備える。そして、芯部１と表層部２とが密着していない状態における芯部１の発泡樹脂は、算術平均粗さＲａが５９μｍ以下であり、かつ、表面のセルの最大径が０．６ｍｍ以下である積層強化複合材料積層体１０。【選択図】図１
