A method for manufacturing a molded article that has a first portion, and a second portion that rises up from the first portion, the method comprising: placing a second material on a surface of a first material; the first material containing a reinforcing fiber A with a length exceeding 30 mm and a thermoplastic resin B, the reinforcing fiber A being dispersed in the first material, and the second material containing a reinforcing fiber a with a length of 1 to 30 mm and a thermoplastic resin b, the reinforcing fiber a being dispersed into the second material, and simultaneously forming the first portion and the second portion by one stroke of pressing, with a cohesive strength of the thermoplastic resin B and the thermoplastic resin b of 2 N/15 mm or larger, the cohesive strength being measured by stacking a 15 mm-wide, 0.03 mm-thick film derived from the thermoplastic resin B, and a 15 mm-wide, 0.03 mm-thick film derived from the thermoplastic resin b; pressing the stack under a pressure of 0.1 MPa, at a temperature 1°C higher than the melting point of the thermoplastic resin B or the thermoplastic resin b, whichever is higher, for two seconds, so as to heat seal the films partially; pulling the films at unsealed portions in the direction 180° away from each other; and finding the force at which the heat-sealed portion separates, or the force at which the resin films rupture before being separated; characterized in that the first material is a commingled yarn that contains, as the fiber components thereof, the reinforcing fiber A with a length exceeding 30 mm, and a thermoplastic resin fiber that contains the thermoplastic resin B; or an article obtained by knitting or weaving the commingled yarn; and the second material is a material chopped into 1 to 30 mm length from a commingled yarn that contains, as the fiber components thereof, the reinforcing fiber A with a length exceeding 30 mm, and a thermoplastic resin fiber that contains the thermoplastic resin B. placing a second material on a surface of a first material; the first material containing a reinforcing fiber A with a length exceeding 30 mm and a thermoplastic resin B, the reinforcing fiber A being dispersed in the first material, and the second material containing a reinforcing fiber a with a length of 1 to 30 mm and a thermoplastic resin b, the reinforcing fiber a being dispersed into the second material, and simultaneously forming the first portion and the second portion by one stroke of pressing, with a cohesive strength of the thermoplastic resin B and the thermoplastic resin b of 2 N/15 mm or larger, the cohesive strength being measured by stacking a 15 mm-wide, 0.03 mm-thick film derived from the thermoplastic resin B, and a 15 mm-wide, 0.03 mm-thick film derived from the thermoplastic resin b; pressing the stack under a pressure of 0.1 MPa, at a temperature 1°C higher than the melting point of the thermoplastic resin B or the thermoplastic resin b, whichever is higher, for two seconds, so as to heat seal the films partially; pulling the films at unsealed portions in the direction 180° away from each other; and finding the force at which the heat-sealed portion separates, or the force at which the resin films rupture before being separated; characterized in that the first material is a commingled yarn that contains, as the fiber components thereof, the reinforcing fiber A with a length exceeding 30 mm, and a thermoplastic resin fiber that contains the thermoplastic resin B; or an article obtained by knitting or weaving the commingled yarn; and
