Abstract
Provided are an electrode material and an electrode which, when an electrode active material having a carbonaceous coat formed on the surface is used as an electrode material, have a small variation in an amount of the carbonaceous coat being supported and, furthermore, can improve electron conductivity, and a method of manufacturing the electrode material. The electrode material is made of an agglomerate formed by agglomerating particles of an electrode active material having a carbonaceous coat formed on a surface, the average particle diameter of the agglomerate is in a range of 1.0 μm to 100 μm, the volume density of the agglomerate is in a range of 50% by volume to 80% by volume of the volume density of a solid form of the agglomerate, the pore size distribution of pores in the agglomerate is mono-modal, and the average pore diameter in the pore size distribution is 0.3 μm or less.
