Abstract: PURPOSE: A manufacturing method of an electrode is provided to reduce the internal resistance between a metal current collector and an electrode active material through two heat treatment processes and to improve the output performance of an electrode by improving electrochemical stability in an electrode material. CONSTITUTION: A manufacturing method of an electrode for a lithium secondary battery comprises a step of manufacturing a slurry mixture by mixing an active material powder, a binder powder, and a conducting powder; a step of making the mixture penetrate into the inner pores of metal foam, conducting a first heat treatment, and forming an electrode layer; a step of a pressing the electrode layer; and a step of conducting a second heat treatment under a reduction atmosphere. [Reference numerals] (S1) Step of manufacturing a slurry mixture by mixing an active material powder, a binder powder, and a conducting powder; (S2) Step of producing a electrode layer by first heating processing after penetrating the mixture of the S1 step inside a gap of the foaming metal; (S3) Step of pressuring the electrode layer produces in the S2 step; (S4) Step of conducting a second heat treatment of the electrode layer produced in the S3 step under a reduction atmosphere
