PROBLEM TO BE SOLVED: To provide a shield structure which can prevent a cover from being unopened due to the flow-in of solder to the cover when a shield constituted of the cover and a base is mounted automatically. SOLUTION: A shield 1 is constituted of a double structure of a box-shaped cover 2 and a box-shaped base 3 having a largely opened top surface 3a, and a material whereto solder does not fix is adopted as the cover 2. Therefore, when the shield 1 is mounted automatically, it is possible to prevent the cover from being unopened due to the flow-in of solder to the cover 2. COPYRIGHT: (C)2005,JPO&NCIPI
