Zusammenfassung:	Provided is a fiber-reinforced composite material shaped product having isotropy and mechanical strength and a random mat used as an intermediate material thereof. The random mat includes reinforcing fibers having an average fiber length of 3 to 100 mm and a thermoplastic resin, in which the reinforcing fibers satisfy the following i) to iii). i) A weight-average fiber width (Ww) of the reinforcing fibers satisfies the following Equation (1). 0.03 mm < Ww < 5.0 mm ii) An average fiber width dispersion ratio (Ww/Wn) defined as a ratio of the weight-average fiber width (Ww) to a number-average fiber width (Wn) of the reinforcing fibers is 1.8 or more and 20.0 or less. iii) A weight-average fiber thickness of the reinforcing fibers is smaller than the weight-average fiber width (Ww).
