PURPOSE: A shuttlecock is provided to enable a user to play a game alone and to receive the same effect as playing a real badminton game by adjusting weight and elasticity appropriately. CONSTITUTION: A shuttlecock includes: a shuttlecock part(100) which has an elastic member which can bounce over 50cm in a free fall experiment at two meters; and a wing portion(200) which is linked to the shuttlecock part and generates air resistance. The elastic member includes: a lining member comprising a fliver; and a cover member which is equipped outside the lining member. A dimple is installed to reduce air resistance at the outside of the cover member. The elastic member has a ball shape having fixed resilience.
