摘要： The present invention provides a method for producing a lithium secondary battery in which peeling of an active substance can be prevented and the generation of metal powder canbe prevented when a power collection foil is processed at an electrode production step. The method for producing the lithium secondary battery includes an electrode-producing step of producing a positive electrode and a negative electrode; a step of forming a group of electrodes by layering the positive electrode and the negative electrode on each other through a separator, or winding the positive electrode and the negative electrode through a separator; and a step of immersing the group of the electrodes in an electrolyte. The electrode-producing step has a boring step of forming a plurality of through-holes penetrating a power collection foil and having projected parts projected from at least a rear surface of the power collection foil and a mixed agent-forming step of forming a mixed agent layer on the power collection foil through which the through-holes have been formed. After the boring step finishes, the mixed agent-forming step is successively performed without winding the power collection foil through which the through-holes have been formed.
