An object is to provide a magnetic recording medium excellent in an electromagnetic conversion characteristic and traveling performance. The present technology provides a magnetic recording medium including a magnetic layer containing a magnetic powder, the magnetic recording medium having an average magnetic cluster size of 1850 nm2 or less, the average magnetic cluster size measured on the basis of an MFM image of a surface on a side of the magnetic layer, the magnetic layer containing first particles having conductivity and second particles having a Mohs hardness of 7 or more, in which protrusions are formed by the first particles and protrusions are formed by the second particles on the surface on the side of the magnetic layer, and a ratio (H1/H2) of an average height H1 of the protrusions formed by the first particles to an average height H2 of the protrusions formed by the second particles is 2.00 or less.
