A nanogranular magnetic film includes first phases comprised of nano-domains dispersed in a second phase. The first phases include Fe and Co. The second phase includes at least one selected from the group consisting of O, N, and F. A CV of Fe/(Fe+Co) of grids is 0.150 or more and 0.500 or less, provided that a measurement range is determined in the nanogranular magnetic film, the measurement range is divided with the grids including at least 80,000 grids each measuring 1 nm×1 nm×1 nm, and Fe/(Fe+Co) of each of the grids is measured in atomic ratio.
