First, a sample holder (13, 57) is lowered such that a sample is held. Next, a roller (11) or a plate-shaped member (56) is lowered and pressed to an adhesive surface (15A) of a sample (15). At this time, a tape (23) is disposed between the roller (11) or the plate-shaped member (56) and the adhesive surface (15A) of the sample (15), and a fixed pressure load is applied to the sample (15). Then after a fixed period of time has passed, the tape (23) is pulled from the sample (15) by the raising of the roller (11) or the plate-shaped member (56) and an adhesive strength is measured with a load cell (25) according to the tension of the tape (23) at that time. After measuring, a take-up reel (21, 52) is rotated so as to wind up a predetermined pitch of the tape (23), and an unused portion of the tape (23) is reeled out to the tip of the roller (11) or the plate-shaped member (56).
