To form a good-appearance stitch pattern while preventing ravel of a thread during stitch processing.SOLUTION: In a manufacturing method for a stitch-processed component 10, a thread 2 locked to a thread hole 14 made through a leading end part 13 of a sewing needle 1 is inserted into a rear surface side of a base material 3 together with the sewing needle with a predetermined pitch, then, a loop portion 21 of the thread is formed on the rear surface side of the base material when the locked thread is pulled back, and the base material and so on restrain the root part 22 thereof, thereby sewing a stitch pattern 20 of the thread fitted in a stitch groove 5 formed in a front surface side of a skin material. The thread hole is formed through the front outer peripheral face and rear outer peripheral face of the sewing needle. In addition, the needle-tip-side internal wall part 141 of the thread hole has a needle-tip-side internal wall face 141P in which a part 142 intersecting the front outer peripheral face is located further on a basal-end side than a part 143 intersecting the rear outer peripheral face. To pull back the sewing needle, the thread locked in the thread hole is slid radially outward from the rear outer peripheral face by use of the needle-tip-side internal wall face, and a loop portion of the thread is formed only on the rear side of the sewing needle.SELECTED DRAWING: Figure 1

    【課題】ステッチ加工時における糸のほつれを防止しつつ、見栄えの良いステッチ模様を形成すること。【解決手段】縫い針1の先端部13に穿設した糸孔14に係止した糸2を、所定のピッチで縫い針と共に基材3の裏面側まで挿通した後、引き戻すときに基材の裏面側に糸のループ部分21を形成し、その根元部22を基材等が拘束することによって、表皮材の表面側に形成したステッチ用凹溝5内に嵌入させた糸のステッチ模様20を縫製するステッチ加工部品10の製造方法である。糸孔は、縫い針の表側外周面と裏側外周面とを貫通して形成され、且つ糸孔の針先側内壁部141には、表側外周面との交差部142が裏側外周面との交差部143より基端側に位置する針先側内壁面141Pが形成され、縫い針を引き戻すときには、糸孔に係止した糸を針先側内壁面によって裏側外周面より径方向外方へ滑動させて、糸のループ部分を縫い針の裏側のみに形成させる。【選択図】図1
