Knitting method of knitted fabric base material and knitted fabric base material

The present invention provides a method for knitting a knitted fabric base material, which can prevent the occurrence of strength unevenness without affecting the orientation of warp yarns and weft yarns because the knitted fabric base material having a pattern is represented by fixed yarns. A method for knitting a knitted fabric base material (1) provided with a base material (2) provided in a plurality of layers such that warp yarns (first base yarns (10)) and weft yarns (second base yarns (20)) comprising reinforcing fiber yarns intersect each other, and knitting yarns (3) for fixing the plurality of layers of base material (2) by a knitted fabric, the knitting yarns (3) being formed by knitting a plurality of warp yarns (first base yarns (10)) and a plurality of weft yarns (second base yarns (20)), the knitting yarns (3) being formed by knitting a plurality of warp yarns (first base yarns (10)) and a plurality of weft yarns (second base yarns (20). The surface of the knitted fabric base material (1) is pa
