1. A cable modem device comprising:
- a first case member which shields a first circuit substrate configured to process at least analog signals;
a second case member to house and shield a second circuit substrate on which the first case member is positioned together with the first case member, the second circuit substrate configured to process at least digital signals;
an electric connection terminal disposed on and intersecting the second case member, the electric connection terminal configured to accommodate in input/output of signals between the second circuit substrate and an external device; and
another electric connection terminal intersecting with the first case member and configured to accommodate input/output of signals between the second circuit substrate and the first circuit substrate.

Abstract
There is discolsed a cable modem device capable of reducing unnecessary signals inputted into a circuit substrate which processes signals and signal terminals from the outside and unnecessary radiation generated by the circuit substrate, the device having a hexahedral shield case which shields a circuit substrate, and a plurality of terminals for use in input/output of the signals with respect to the circuit substrate. Each of the terminals has a noise filter function, and is fixed to the shield case.
