Abstract

PROBLEM TO BE SOLVED: To provide a mounting structure of a shield case which eliminates the need for a solder removing work in a removing step for reducing the manufacturing man-hours and improves the shield effect. SOLUTION: A shield case 5 is constituted of a body and top cover integrated with it. For mounting the case 5 on a printed wiring board 1, mounting components 3-1 to 3-5 fixed to the printed wiring board 1 are inserted into notches 6-2 to 6-4 at the opening. The mounting components 3-1 to 3-5 contain mounting springs 4-5 which nip and grip the four wall end edges of the opening of the case 5. After inserting the legs of the mounting components 3-1 to 3-5 in through-holes 2-1 to 2-5 of the printed wiring board, they are soldered to be fixed.
