PROBLEM TO BE SOLVED: To provide a particle for electrode which is suitable as a negative electrode material for a lithium ion secondary battery and has a high lithium storage and release capacity, and is hardly broken even if continuous charge and discharge are repeated. SOLUTION: The particle for electrode contains a metal particle to form an alloy with lithium, a conductive carbon material, and a binding resin and has a gap in the interior, and is manufactured by a process in which a compound particle consisting of the metal particle which forms an alloy with lithium, the conductive carbon material, and a resin component is prepared by mechanically mixing and pulverizing and a process in which the compound particle is heated on a condition in which only a part of the resin component is decomposed and volatilized.
