Abstract
Abstract A shield structure for use in an electronic apparatus includes a shield case for covering a first and second circuitry block and for isolating each other. In order to enhance the electrical connection of the shield case to a first ground on a first circuit board and a second ground on a second circuit board, a conductive component is fastened to the shield case. The conductive component includes a fastening portion, a first contact portion contacting the first ground, and a second contact portion contacting the second ground.
