1. A sewing method for a cover material, comprising:
- sewing a plurality of cover pieces together with a sewing machine to form a cover material that covers a vehicle structure member;
arranging a plurality of conductive threads that extend linearly parallel to each other in at least one of the plurality of cover pieces;
forming a stitch line formed of a plurality of perforations that crosses the plurality of conductive threads, by passing a sewing needle of the sewing machine through the cover material at a predetermined pitch, while moving the cover material at a predetermined feed rate with respect to the sewing machine; and
providing the sewing machine with a sensor member, and changing a position through which the sewing needle will pass to a position other than a position where the plurality of conductive threads are arranged, which is different from an initially set position, by changing the feed rate of the cover material, after detecting one of the plurality of conductive threads that is arranged in front, in a direction of travel, of the sewing needle.

Abstract
A sewing machine is provided with a sensor member, and a feed rate of cover pieces is changed after detecting a conductive thread that is arranged in front, in a direction of travel, of a sewing needle. A position through which the sewing needle will pass is changed to a position other than a position where the conductive thread is arranged, which is different from an initially set position.
