To provide an electrical device that can reduce assembly cost, and can surely operate in spite of it.

This compact electrical devices, especially circuit network components, are equipped with at least one inductance and a contact-connecting device that can be connected to a reference voltage, and combines the inductance with the contact-connecting device via conductive connection. In this case, inductance 3 and/or a first conductive connection part 2 and/or contact- connecting devices 4 and 5 are at least partially arranged in a support which is made of an insulation material, and at the same time, are mutually insulated by the material of the support 1. In addition, an electrical circuit device 11 is combined with the first conductive connection part 2 of the support 1 via a second conductive connection part 12.
