摘要： A measurement apparatus for corrosion inspection is an apparatus that takes a measurement for corrosion inspection of an inspected object having a metal base material and surface-treated films on the base material, and includes: a contact section that holds an aqueous electrolyte material and contacts a surface of the surface-treated film; and a measurement section that has an electrode electrically connected to the surface-treated film via the contact section, and measures an energized state between the electrode and the base material while applying a voltage between the electrode and the base material. At least a portion of the contact section is a sheet having a water retention characteristic for holding the aqueous electrolyte material. The contact section is switched between a spread-out state where the contact section is spread out and contacts the surface of the surface-treated film during measurement and an accommodated state where the contact section is reduced in size during a non-measurement period.
