To provide a magnetic recording medium with which excellent electromagnetic conversion characteristics can be obtained. A magnetic recording medium is a tape-type magnetic recording medium and includes a base body and a magnetic layer. An average thickness of the magnetic recording medium is 5.30 μm or less. When a power spectral density at each position of spatial wavelength λn=100/n [μm] (provided that n is an integer of 1 or more and 255 or less) is obtained using a 2D surface profile image of a measurement range of 100 [μm]×100 [μm], that has been acquired by measuring a surface on a side of the magnetic layer by an atomic force microscope, a ratio Iλn≤5/I10≤λn≤20 between an average value Iλn≤5 of integrated values of the power spectral density within a range of spatial wavelength λn≤5 μm and an average value I10≤λn≤20 of integrated values of the power spectral density within a range of 10 μm≤spatial wavelength λn≤20 μm is 3.00 or less. An average value of a kurtosis on the surface on the side of the magnetic layer is 5.50 or less.
