Abstract
There is provided a thermoplastic resin pellet containing a thermoplastic resin (A) and a fibrous filler (B), in which a length-weighted average fiber length of the fibrous filler (B) is 5 mm or more and less than 50 mm, a pellet length of the thermoplastic resin pellet and the length-weighted average fiber length of the fibrous filler (B) are substantially the same, and a maximum cross-sectional height Rt of a surface of the thermoplastic resin pellet is less than 120 μm.
