PROBLEM TO BE SOLVED: To provide a PT plate shield structure in which leakage of electromagnetic wave from the end of a printed board is prevented without providing a large number of through holes in the circumferential fringe of the printed board. SOLUTION: Since an onboard contact 1 is imparted with resiliency in the horizontal direction and the onboard contact is energized to the inner side face of a shield case 3 covering the end 2a of a printed board 2, the printed board can be shielded over the entire circumference thereof so that electromagnetic wave does not leak from anywhere. Furthermore, since the onboard contact comprises an L-shaped rigid part 3a and a resilient part 3b formed by bending the upper end of the rigid part outward several times and a cut is made in the resilient part in the vertical direction, the resilient part is deformed and recovered more appropriately to ensure good contact. The shield case can be kept at the ground potential of the printed board and the printed board can be shielded surely.
