In a core/sheath type temperature-sensitive shape-transformable composite filament comprising a thermoplastic resin (A) and a thermoplastic polymer (B) having a glass transition temperature within the range of from 0°C to 70°C, the composite filament is constituted in proportions satisfying the following expressions (1), (2) and (3). In the core; (A)/(B) = 5/95 to 90/10 (% by weight) (1) In the sheath; (A)/(B) = 100/0 to 50/50 (% by weight) (2) Core/sheath = 10/90 to 95/5 (% by weight) (3) The filament is useful as doll hair the hair style of which is thermally shape-transformable to any desired shapes even by infants , and is easily fixable to the transformed shape by cooling.
