A material, comprising: a first region (1), a fiber region (2), and a second region (3), continuous in a thickness direction; the first region and the second region each independently being a resin layer including 20% to 100% by mass of a thermoplastic resin component and 80% to 0% by mass of reinforcing fibers; the fiber region including 20% to 100% by mass of thermoplastic resin fibers and 80% to 0% by mass of reinforcing fibers; the thermoplastic resin component included in the first region and the thermoplastic resin component included in the second region each independently having a crystallization energy during a temperature rise of 2 J/g or more, as measured by differential scanning calorimetry; and the thermoplastic resin fibers included in the fiber region having a crystallization energy during a temperature rise of less than 1 J/g, as measured by differential scanning calorimetry; where the crystallization energy during a temperature increase is a value measured by using a differential scanning calorimeter (DSC) in a stream of nitrogen, while heating from 25 °C to a temperature that is 20 °C higher than a melting point of the thermoplastic resin component or the thermoplastic resin fibers at a temperature rise rate of 10 °C/min. |
