(57) To provide a knitting method of a three dimensionally (3D) shaped-knitted fabric with which a 3D shaped-knitted fabric having a complex shape than the related art can be knitted. The knitting method includes a base knitting step in which a base knitted fabric portion including four sides is knitted such that at least three sides of the four sides are held on the needle beds; and a projection knitting step in which a projecting knitted fabric portion is knitted from at least one side of the base knitted fabric portion such that the projection knitted fabric portion has a smaller knitting width than the relevant one side. In the projection knitting step, moving a part of a stitch row configuring one side of the base knitted fabric portion toward the outer side in a knitting width direction, knitting a pickup stitch on the knitting needle that became an empty needle by such movement, and forming a part of one side of the projecting knitted fabric portion; and knitting a new stitch row following a stitch row proximate to the empty needle to increase the knitting course of the projection knitted fabric portion are repeated.
