摘要：
A production method of an electrode for a lithium-ion secondary battery includes: (A) a step of providing a current collector 11 having a plurality of bumps 12 on a surface thereof; (B) a step of allowing an evaporated source material to strike from a direction E which is tilted with respect to the normal of the surface of the current collector 11 to form a corresponding plurality of pillar-like members 14 on the plurality of bumps 12; and (C) a step of oxidizing the plurality of pillar-like members 14 to form a plurality of active material members 18 containing an oxide of the source material.
