Provided is a metal coating material which is capable of minimizing heat generation accompanying the oxidation during when a seed is coated while having excellent workability during when heat is dissipated and exhibiting excellent adhesion strength with respect to the seed. A metal coating material (10) which coats a seed (20) by having a metal powder (11) which is mainly composed of iron and contains at least granular fine particles (11A) and plate like fine particles (11B) adhere to the seed (20). The ratio of the particles having a size of 63 150 µm in the particle size distribution of the metal powder (11) as determined using a JIS test sieve is 23% by weight or more.
