To provide a composite slab capable of improving strength and stiffness by improving the shear force transmission performance between the reinforced concrete slab and the wooden surface material.SOLUTION: A composite slab 101 includes: a wooden surface material 30 having an upper surface 31 and a lower surface 32 opposed to each other in the thickness direction; and a reinforced concrete slab 50 that is laminated on the upper surface 31 of the wooden surface material 30. On the first surface 31 of the wooden surface material 30, multiple first slits 71 extending along the first direction are formed at predetermined intervals in a second direction intersecting a first direction that intersects with the direction in which the main reinforcement 61 of the reinforced concrete slab 50 extends, and inside of a first slit 71 is filled with a concrete 51 of the reinforced concrete slab 50.SELECTED DRAWING: Figure 1 【課題】鉄筋コンクリートスラブと木質面材との間のせん断力の伝達性能を向上させて、耐力及び剛性の向上を図ること。【解決手段】合成スラブ１０１は、板厚方向に対向する上面３１及び下面３２を有する木質面材３０と、木質面材３０の上面３１の上に積層された鉄筋コンクリートスラブ５０と、を備え、木質面材３０の第１面３１には、鉄筋コンクリートスラブ５０の主筋６１が延在する方向と交差する第１方向に延び、第１方向と交差する第２方向に所定の間隔を置いて複数の第１スリット７１が形成され、第１スリット７１の内部に鉄筋コンクリートスラブ５０のコンクリート５１が充填されている。【選択図】図１
