PROBLEM TO BE SOLVED: To improve handling property of a 135-type photographic film using a polyester base body after the film is loaded in a camera. SOLUTION: This 135-type photographic film consists of a base body of a copolymer polyester film having ethylene-2,6-naphthalate repeating units and ethylene terephthalate repeating units, and at least one silver halide emulsion layer on the base body. The copolymer polyester film has 95 to 130μm film thickness, 350 to 500 kg/mm<2> Young's modulus in the longitudinal direction, and 450 to 600 kg/mm<2> Young's modulus in the width direction, satisfying that the Young's modulus in the width direction is larger than that in the longitudinal direction. |
