With relation to a first test piece with an adhesive applied thereto, a second test piece is swiftly moved close to the contact bonding position by a movable actuator, and then the second test piece is pressed by a pressing actuator on the first test piece for contact bonding. When the both test pieces joined together are peeled from one another, a peel load is detected by a load cell via a table which is supported by the load cell and on which the test pieces are fixed. If a corrugated board is used as a test piece, it is held by a holding member consisting of a plurality of parallel needles which have been inserted from the side into the intermediate portion between one surface and another of the test piece and common frame members for securing the ends of the needles.
