PROBLEM TO BE SOLVED: To provide an item storage tray that causes a short-circuit between the upper and lower conductive coating layers by means of a simple structure. SOLUTION: A cut 21 is vertically made in the tray surface, in a part that is adjacent a recess 3. Of a pair of cut fragments 11 and 12, which are defined by the cut 21 so as to be separated, the cut fragment 11 on the side of the recess 3 is placed on the other cut fragment 12. Thus, the conductive coating layer 6 disposed underneath the cut fragment is engaged with the conductive coating layer 5 disposed on the cut fragment. |
