The present invention provides a knitted fabric and a method for knitting knitted fabric. The knitted fabric is provided with an edge knitted fabric part which is arranged next to an opening at central part of a substrate knitted fabric and turns back to outside of the opening for overlapping with the substrate knitted fabric part. The edge knitted fabric part (2) comprises a first coil (21), a second coil (22) and a third coil (23). The knitting width direction ends (e-g,i-k) of the first coil (21) and the second coil (22) are connected with the substrate knitted fabric (1). The longitudinal direction end (1-m) of the third coil (23) is connected with the substrate knitted fabric (1). Additionally, the longitudinal direction end (g-f) of the first coil (21) is connected with the knitting width direction end (1-n) of the third coil (23). Furthermore the longitudinal direction end (k-j) of the second coil (22) is connected with the knitting width direction end (m-o) of the third coil (23).
