There is provided a shaped product made of a fiber-reinforced composite material including reinforcing fibers having an average fiber length of 5 to 100 mm and a thermoplastic resin. In the shaped product, a volume fraction of reinforcing fibers is 5 to 80%, a reference plane (S) and a standing plane (B) inclined at an angle of 45 to 90 degrees with respect to the reference plane are included, a ratio of an area of the standing plane (B) to an area of the reference plane (S) is 0.5 to 100, and in the fiber-reinforced composite material constituting the shaped product, a ratio of a reinforcing fiber bundle (A) including the reinforcing fibers of a critical number of single fiber or more to the total amount of the reinforcing fibers is 20 Vol % or more and 99 Vol % or less.
