PROBLEM TO BE SOLVED: To obtain a method capable of measuring the cross-sectional shapes, angles, etc., of blades by non-destructive inspection. SOLUTION: An impression of a measuring part of an elastic body 1c of an elastic body blade 1 is imparted to an impression forming material 5 in an unset state, and the set impression forming material 5 is pulled out from the elastic body blade 1. The impression forming material 5 is cut in a longitudinal direction and an orthogonal direction at any locations to measure the angles and circular radii of a part to which an edge 2a, which is a section to be measured of the elastic body blade 1, is transcribed. It is possible to accurately and non-destructively measure even a material such as a rubber material which is easily deformed or bent by a stylus or a material swollen with a liquid such as oil.
