Abstract

An electrode for a nonaqueous electrolyte secondary battery includes a current collector and an electrode material disposed on the current collector. the electrode material has a thickness of 50 μm or larger. The electrode material contains at least active material particles, an electro-conductive material, and a crack preventive material. An average particle diameter of the crack preventive material is two times or larger than an average particle diameter of the active material particles.
