Abstract
A random mat material including fiber bundles, said fiber bundles including fibers having an average fiber length of 5 to 100 mm, and having an average number N of fibers in the fiber bundle that satisfies: wherein D is the average diameter of fibers in the fiber bundle, expressed in micrometers, and the standard deviation SDof the number of fibers in a fiber bundle satisfies:1,000<SD<6,000wherein at an end of the fiber bundle, the number of the fibers in a fiber bundle becomes less from center to edge of the fiber bundle in a fiber direction.
