The present invention provides technology capable of weaving a high-density textile. The loom (100) of the present invention comprises: multiple heddles (6) which make some warps (1A) of multiple warps (1) separated from other warps (1B); a weft guiding portion (10) making wefts (2) pass through an opening (9); a reed (7) pressing the wefts (2) passing through the opening (9) towards a fell (8) so as to form a textile (11); a feeding roller (4) which feeds the warps (1) to the heddles (6) at a position that deviates and staggers from an imaginary plane (VP) passing through the center (C) of the moving range of the heddles (6) and the fell (8); a delivery loom beam (3) delivering the warps (1) to the feeding roller (4); and a textile winding loom beam (15) winding the textile (11), when the heddles (6) is at the center, the tension of the warps (1) being set as 0.32 cN/dTex or more and 0.38 cN/dTex or less.
