Method for manufacturing electrode

Provided is a method for manufacturing an electrode capable of stably manufacturing an electrode having an electrode mixture layer having a desired film thickness. The method is provided with: a step for detecting the surface position of a composite coating film (B) by means of a first sensor (42); a step in which the surface position of the second roller (20) is detected by a second sensor (44); a step for detecting the film thickness of the composite material coating film on the basis of the difference between the detection results of the first sensor and the second sensor; and a step for adjusting the ratio of the rotational speed of the third roller (30) to the second roller on the basis of the film thickness of the composite coating film. The detection positions of the first sensor and the second sensor in the circumferential direction of the second roller are substantially the same. As a result, it is possible to detect the accurate film thickness of the composite coating film from which the influence c
