The second silver halide photosensitive material comprises a substrate and at
least one photosensitive silver halide emulsion layer formed thereon, the silver
halide photosensitive material comprising at least two types of silver halide grains
with different projected areas having photosensitivity in the same spectral range;
silver halide grains having a larger projected area having a refractive index n1
and an average thickness a, and silver halide grains having a smaller projected
area having a refractive index n2 and an average thickness b; and the silver halide
grains satisfying the conditions defined by the following equation (1):
