A stampable sheet which comprises a resin and a carbon fiber sheet constituted of fiber bundles of discontinuous carbon fibers, wherein the carbon fiber sheet comprises fiber bundles (A) having a bundle width of 50 µm or greater and opened fibers (B) ranging from fiber bundles having a bundle width less than 50 µm to fibers obtained by opening to the single-fiber level. When the direction along which the opened fibers (B) have been oriented most is taken as 0° direction and the range of from the 0° direction to a 90° direction is divided into a plurality of angular zones, the distribution curve which shows the proportion of the number of fiber bundles (A) in each angular zone to that in all angular zones and the distribution curve which shows the proportion of the number of opened fibers (B) in each angular zone to that in all angular zones are reverse to each other in terms of gradient in the range of from the 0° direction to the 90° direction. This stampable sheet can exhibit high mechanical properties with a high isotropy, and makes it possible to easily mold a desired CFRP with a satisfactory moldability.
