<p>PROBLEM TO BE SOLVED: To provide a chemical state measuring method which achieves accurate measurement of a chemical state of a surface of a rubber material, especially a change of the chemical state, which is caused from the surface, such as deterioration (deterioration state of the rubber material).SOLUTION: In a chemical state measuring method, a surface analysis method using an X-ray is applied after a bloomed material is removed from a surface of a rubber material, so that a chemical state of the surface of the rubber material is measured.</p> |
