PROBLEM TO BE SOLVED: To provide a check pattern and packaging evaluation device, for performing the loading evaluation of a semiconductor chip, by easily and surely detecting a damage generated on the outside of a guard ring. SOLUTION: In a detection part 20, a plurality of electric circuits 2 are connected in parallel, or arranged in parallel with a predetermined interval, from a scribing area 6 for dicing to the outside area of the guard ring 4, toward the inner side of the semiconductor chip 5a. An output terminal 3 is connected to the detection part 20, and arranged on the outside of the guard ring 4. The condition of the damage generated on the outside area of the guard ring 4 is analyzed, based on a deviation amount of impedance owing to a break in the electric circuits 2.
