The present Disclosure discloses an artificial shuttlecock, which includes a base portion, a plurality of stems, a plurality of feathers, a first connecting element, a second connecting element and at least one third connecting element. The base portion includes a concave portion. One end of the stem connects to the base portion, and the feather connects to the other end of the stem. The first connecting element connects to the stems, and is close to the base portion. The second connecting element connects to the stems, and is close to the feathers. The third connecting element connects to the stems, and is located between the first connecting element and the second connecting element.

The present disclosure discloses a synthetic shuttlecock, which includes a base portion, a plurality of stems, and a plurality of feathers. One end of each of the stems is inserted into the base portion. Two of the feathers are connected to one of the stems. A connecting portion is formed on the stem, respectively. Each of the feathers has a first length and a first width. Each of the feathers has two holes, the two holes are located on the two sides of the connecting portion respectively, and the holes are close to a front end of the connecting portion. Each of the holes has a second length and a second width. The ratio of the second length to the first length is between 0.22 and 0.31, and the ratio of the second width to the first width is between 0.06 and 0.28.
