摘要：PURPOSE:To judge a peeling point of a thin film from a base material while enabling accurate measurement of a peeling load by determining a testing point with an optical monitor to apply a peeling load to a plane indenter after it is bonded on a thin film sample. CONSTITUTION:An optical image of a base material sample 17 formed with an optical monitor 30 is taken with a TV camera 33 to be stored into an image memory 35 and projected onto a CRT 36 to determine a testing position of a thin film on the surface of the sample 17. Then, the thin film is bonded on a plane indenter 7 by putting an adhesive on the plane indenter 7. A load is generated with a load current feeder 13 so as to lift the indenter 7. In this manner, a tensile load is applied continuously to the thin film to measure a load as peeling load at which a peeling occurs between the thin film and the base material 17. This enables accurate measurement of a peeling load of the thin film sample thereby accomplishing an evaluation of the strength of the thin film accurately.
