摘要：Problem to be solved: to provide a shield structure capable of electromagnetic
shielding for a shielding space area necessary for a functional circuit unit. The ball bump
on the base substrate side is electrically connected to the ground electrode of the base
substrate to form a bump of a predetermined height arranged in the peripheral portion
surrounding the functional circuit with respect to the upper surface of the base
substrate, and the frequency of the ball bump arrangement is used The insulating
substrate is provided with an insulating substrate, a conductive surface and a connection
electrode on the cover substrate side which is arranged at a predetermined interval
corresponding to the band, and the surface mounting part is formed, and the insulating
substrate is at least the insulating material having a predetermined dielectric
characteristic at least in order to cover the whole of the functional circuit A conductive
surface is formed on the entire upper surface of the insulating substrate, a metal
conductive surface is formed, the connection electrode is electrically connected to the
conductive surface, and the connection electrode is formed at a position corresponding
to the ball bump which is opposed to the base substrate side, and the cover substrate is
applied to the ball bump of the base substrate A shield structure on a circuit board which
has an abutment connection in nature and has a high frequency functional circuit to be
magnetically shielded.
