Claims

[Scope of utility model registration request]

A plate-like member provided on the slope of a printed wiring board and between components mounted on the printed wiring board, and having a through hole provided for each lead to allow the leads of the component to pass to the printed wiring board, and the above component. A ferrite core is provided in every through hole corresponding to a predetermined lead among the leads, and is attached to the through hole in a shape that increases the self-inductance and cotance of the lead passing through the through hole. module filter.
