Abstract
A stampable sheet includes a resin and carbon fiber sheet including fiber bundles of discontinuous carbon fibers, wherein the carbon fiber sheet includes fiber bundles having a bundle width of 50 μm or greater and opened fibers 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 have been oriented most is a 0° direction and the range of from the 0° to 90° direction is divided into angular zones, the distribution curve showing the proportion of the number of fiber bundles in each angular zone to that in all angular zones and the distribution curve showing the proportion of the number of opened fibers in each angular zone to that in all angular zones are reverse to each other in terms of gradient of the 0° to 90° direction.
