A method of knitting a tubular fabric including an integrated tubular portion and a plurality of branched tubular portions (4,5) which are continuously formed in a wale direction of the integrated tubular portion and which are independent from each other using a flat knitting machine having at least a front and a back needle beds (FB,BB) and capable of transferring a stitch held on a knitting needle of the needle bed to another knitting needle, the method comprising: step α of knitting the integrated tubular portion; characterized by step β of forming a plurality of held stitches held on the knitting needle by feeding a knitting yarn alternately to the front and the back with respect to knitting needles of the front and back needle beds (FB,BB) on which stitches of the integrated tubular portion are not held, within a knitting width of the integrated tubular portion; step γ of transferring the held stitches held on the knitting needles of one needle bed of the held stitches formed on the knitting needle in step β to the knitting needles of the other needle bed, performing knitting using some of the knitting needles within a knitting width of the integrated tubular portion including the knitting needles on which the transferred held stitches are held, and starting the knitting of one of the branched tubular portions following the integrated tubular portion; step δ of transferring the stitches, held on the knitting needles of the other needle bed and in a formed range of the held stitches formed in step β, of the stitches knitted in step γ to the knitting needles of the one needle bed; and step ε of transferring the held stitches held on the knitting needles of the other needle bed of the held stitches formed on the knitting needles in step β, which are not the target of transfer in step γ, to the knitting needle of the one needle bed, performing knitting using some of the knitting needles within a knitting width of the integrated tubular portion including the knitting needles on which the transferred held stitches are held, and starting the knitting of another branched tubular portion adjacent to the branched tubular portion which knitting started in step γ. step α of knitting the integrated tubular portion; characterized by step β of forming a plurality of held stitches held on the knitting needle by feeding a knitting yarn alternately to the front and the back with respect to knitting needles of the front and back needle beds (FB,BB) on which stitches of the integrated tubular portion are not held, within a knitting width of the integrated tubular portion; step γ of transferring the held stitches held on the knitting needles of one needle bed of the held stitches formed on the knitting needle in step β to the knitting needles of the other needle bed, performing knitting using some of the knitting needles within a knitting width of the integrated tubular portion including the knitting needles on which the transferred held stitches are held, and starting the knitting of one of the branched tubular portions following the integrated tubular portion; step δ of transferring the stitches, held on the knitting needles of the other needle bed and in a formed range of the held stitches formed in step β, of the stitches knitted in step γ to the knitting needles of the one needle bed; and step ε of transferring the held stitches held on the knitting needles of the other needle bed of the held stitches formed on the knitting needles in step β, which are not the target of transfer in step γ, to the knitting needle of the one needle bed, performing knitting using some of the knitting needles within a knitting width of the integrated tubular portion including the knitting needles on which the transferred held stitches are held, and starting the knitting of another branched tubular portion adjacent to the branched tubular portion which knitting started in step γ.
