1. An electrode for a non-aqueous electrolyte secondary battery comprising:
a current collector; an active material layer that is formed on the current collector; and an aggregate of filler particles that is present on a surface of the active material layer,
wherein the filler particles are particles containing at least one of potassium pyrosulfate, and a compound containing an alkali metal or Br,
a transformation point of the filler particle at which the filler particle is transformed from a solid phase into a liquid phase or is thermally decomposed is in a range of 180 to 650° C.,
the compound containing an alkali metal or Br contains at least one of a borate, a citrate, and an aromatic compound, and
an average particle diameter of the filler particles is 0.05 μm to 3 μm.
