PROBLEM TO BE SOLVED: To provide a line-drawing thread 10 satisfying both of attachability of powder, and strengths and durability. SOLUTION: This line-drawing thread is obtained by twisting a first raw thread 11 for securing the required strength, and a second raw thread 12 having thin fibers 12a for facilitating the cling of the powder, for example, so as to form an eight stranded shape. The first raw thread comprises, for example, a nylon fiber, and the second raw thread comprises, for example, a polyester fiber or a cotton fiber. Preferably, the proportion of the number of the second raw thread based on the number of the whole raw thread is 10-50%. COPYRIGHT: (C)2005,JPO&NCIPI
