Claim:
1. A semiconductor device comprising: a first substrate having a first circuit manufactured thereon; a second substrate having a second circuit manufactured thereon and being arranged to be spaced to the first substrate; a connection part that is arranged between the first substrate and the second substrate and electrically connects the first circuit and the second circuit; and a shielding layer that is sandwiched, together with the connection part, between the first substrate and the second substrate, is arranged so as to surround the connection part, and is connected to an electric potential with a constant value within at least one of the first substrate and the second substrate, wherein, when the signals transmitted and received via the connection part between the first circuit manufactured on the first substrate and the second circuit manufactured on the second substrate are sorted into signals that operate at a low speed and signals that operate at a high speed, the shielding layer is arranged so as to surround the connection part that transmit and receive the signals that operate at the high speed and the shielding layer is not arranged so as to surround the connection part that transmit and receive the signals that operate at the low speed.
