摘要：
A fiber-reinforced multilayered pellet includes a sheath layer and a core layer, the sheath layer being made of a resin composition containing a thermoplastic resin (a1) and a fibrous filler (b1), wherein the fibrous filler (b1) has a weight-average fiber length (Lw) of 0.1 mm to less than 0.5 mm and a weight-average fiber length/number-average fiber length ratio (Lw/Ln) of 1.0 to less than 1.8, the core layer being made of a resin composition containing a thermoplastic resin (a2) and a fibrous filler (b2), wherein the fibrous filler (b2) has a weight-average fiber length (Lw) of 0.5 mm to less than 15.0 mm and a weight-average fiber length/number-average fiber length ratio (Lw/Ln) of 1.8 to less than 5.0.
