Device and method for measuring adhesive strength

An adhesive strength measuring device for measuring an adhesive strength of a sample by pressing a predetermined point of a guide member provided with a predetermined contact surface to the sample, then peeling the pressed contact surface, and measuring the adhesive strength, said device comprising:

• a vertically moveable base plate;
• a load cell connected to said vertically movable base plate to measure adhesive strength;
• a guide member connected to said vertically movable base plate, wherein the guide member is held by a cassette member which is attachable and detachable with respect to a device body;
• a moving mechanism connected to said vertically movable base plate, wherein said moving mechanism is adapted to move an unused portion of the contact surface to a position at which said guide member can press an unused portion of the contact surface to the sample to enable each measurement of the adhesive strength.
