Abstract
A noise reduction unit () is equipped with a noise filter (), a housing () which houses the noise filter, and a sealing material () which is charged in the housing. The noise filter is equipped with conductors () having respective winding portions () and a ring-shaped core () which is made of a magnetic material and is inserted through the winding portions of the conductors. In the housing, a mounting portion () for the ring-shaped core has recesses () that are recessed in a direction going away from the ring-shaped core and support portions () that support the ring-shaped core so that gaps (S) are formed between the ring-shaped core and the bottom surfaces of the respective recesses. The sealing material goes into the gaps and comes into contact with both of the ring-shaped core and the bottom surfaces of the recesses in the mounting portion.
