PROBLEM TO BE SOLVED: To provide a method for relatively and suitably evaluating the strength of respective joining boundaries in a plurality of fillet lap joints. SOLUTION: A test piece 10 is sampled from a one side lap joint obtained by subjecting a planar first base material 12 and a planar second base material 14 to lap fillet welding, the part of the second base material side 14 in the test piece 10 is clamped together with an L-shaped tool 24 in such a manner that a lap fillet welded part 16 is located on the curved face 34 at the outside corner part of the L-shaped tool 24, thereafter, the test piece 10 is subjected to a bending test along the curved face 34 of the L-shaped tool, and the limit of producing boundary peeling in the joined face 18 of the lap fillet welded part 16 of the test piece 10 is inspected.
