MASKING MATERIAL, MASKING METHOD, AND METHOD OF MANUFACTURING COATED MEMBER ON WHICH COATING FILM IS NOT PARTIALLY FORMED

摘要

PROBLEM TO BE SOLVED: To provide a masking material having superior heat resistance and capable of being repeatedly used, a method of manufacturing such a masking material, and a masking method using such a masking material.SOLUTION: A masking part 3 of a masking material 1 containing a magnetic component has a circular shape. The masking part 3 has a central part 4 that is more recessed than a circumferential part 5. In the masking material 1, a radius r (unit: mm) of a circle of the masking part 3, a maximum depth d (unit: mm) of the recess of the central part 4 relative to the circumferential part 5, a magnetic flux density B (unit: T) obtained by the measurement at a position separated by 1 cm in a direction parallel to a central axis of the circle of the masking part from a position giving the maximum depth in the masking part 3, and Shore D hardness Hs of the masking material 1 satisfy all of expressions of 0.045B...(1), 5.5B/(d/r)...(2), and 42Hs60...(3).
