Disclosed is a two-needle sewing machine that improves strength in a convex curve part by bringing a pair of stitches close together when sewing an item to be sewn that includes the convex curve part. A two-needle sewing machine 1 includes a bed part 3; a column part 5; an arm part 6; a needle shaft 11 that is disposed on the leading part of the arm part 6; two sewing needles 13, 14 that are attached to the needle shaft 11; two horizontal hooks 15, 16 that catch the respective needle thread loops of the two sewing needles 13, 14; and a conveyor member 21 that conveys a material to be sewn 40 in a direction approximately orthogonal to the bed part 3. On the two-needle sewing machine 1, the sewing needle 13, which is positioned in a location distant from the column part 5, is disposed closer to the conveyance side of the material to be sewn 40 than the sewing needle 14 that is positioned in a location closer to the column part 5.
