An artificial feather for a shuttlecock including a vane portion in a thin film form, corresponding to a vane, and a rachis portion in a bar form extending integrally and continuously from an upper tip end to a lower distal end, corresponding to a rachis, to imitate a natural feather, the vane portion being made of thermoplastic resin having interconnecting bubbles therein, and having low specific gravity and low elasticity relative to the rachis portion, the rachis portion being made of thermoplastic resin being fixed to the vane portion at a vane support portion, having the vane support portion set as an area that is fixed to the vane portion along the tip end to a bottom end of the vane portion, and having a calamus portion set as an area that protrudes to a lower side of the vane portion and spans from a bottom end of the vane support portion to the distal end, to correspond to a calamus of the natural feather. |
