<P>PROBLEM TO BE SOLVED: To provide an instrument for comparative learning of strength enabling a user to sensuously learn the difference in the strength resulting from the difference in the connecting structure between a frame and a face material. Ž<P>SOLUTION: The instrument for comparative learning of strength comprises: a first model which is so constituted that, by driving a plurality of metal locking pieces to a pair of first face materials sandwiching a first core, the first core and the first face materials are joined; and a second model which is so constituted that, by applying an adhesive on a contacting face between a core and a pair of second face materials sandwiching the core, the second core and the second face materials are joined, and which is nearly identical in appearance to the first model. By applying a prescribed load to the first model and the second model respectively in the thickness direction, the user can compare and learn the degree of difference in bending between both models.
