PROBLEM TO BE SOLVED: To provide the superior heat resistance with a nylon monofilament and to provide the sufficient durability in the use under a high temperature area, by forming a filter for injector by nylon monofilament woven fabric having the strength retention of more than a specific value. SOLUTION: As a nylon monofilament material used in a filter for injector, polyamide such as nylon 66, nylon 6 or the like or a polyamide copolymer can be cited. To improve the heat resistance of the nylon monofilament, copper salt and alkali metallic salt and/or alkali earth metallic salt are included. On this occasion, a blending ratio of the copper salt and alkali metallic salt and/or alkali earth metallic salt is 1: 2 through 2:1, preferably nearly equal to each other. A diameter of the nylon monofilament is more than 25μand less than 50μto stably manufacture the yarn and to easily prepare the woven fabric of high concentration.
