PROBLEM TO BE SOLVED: To provide an in-tank filter material of excellent fuel filtering property and durability reduced in cost with elasticity and excellent filtering property compared with conventional filter materials. SOLUTION: This in-tank filter material of excellent fuel filtering property is formed of nonwoven fabric formed in a laminated fiber layer of coarse-dense structure from one side toward the other side by laminating and integrating two or more mixed fiber layers of high fusing point short fiber and heat-fused short fiber. Polyester short fiber is used as the high fusing point short fiber, while sheath-core compound fiber is used as the heat-fused short fiber, and the effective ratio of both fibers is 10:90-50:50.
