Zusammenfassung:	Provided in the present application are a measurement method and apparatus for an electrode sheet. By means of the present application, the surface density of the entire area of an electrode sheet material can be effectively measured. The method comprises: acquiring a signal of a ray, which irradiates an electrode sheet and transmits through the electrode sheet, wherein the ray is provided in the width direction of the electrode sheet, covers the electrode sheet, and scans the electrode sheet in the lengthwise direction of the electrode sheet; and according to the signal, which is transmitted through the electrode sheet, measuring the surface density of a material with which the surface of the electrode sheet is coated.
