PURPOSE:To make it possible to stably impress electric current for electric protection over a long period of time by setting a meshy insoluble electrode on the surface of a concrete structure, pressing a protective sheet coated with an electrolyte against the surface of the structure with the electrode in-between and fixing the sheet. CONSTITUTION:A linear or meshy insoluble electrode 5 is set on the surface of a concrete structure 1. A protective sheet 6 coated with an electrolyte is pressed against the surface of the structure with the electrode 5 in-between and the coated side inward. The pressed sheet 6 is fixed in the surface of the structure with fixing tools 2, 4.
