MAGNETIC BODY FOR FILTER AND COMMUNICATION CONNECTOR

摘要

PROBLEM TO BE SOLVED: To provide a magnetic body for a filter which can suppress a variation in a high frequency component removal effect due to temperature change.

SOLUTION: A magnetic body for a filter is provided with a magnetic member and a stress generating member which is integrally installed with the magnetic member and whose coefficient of thermal expansion is different from the coefficient of thermal expansion of the magnetic member. At a temperature change, the stress generating member generates a stress in the magnetic member and suppresses a variation in a permeability so that a variation in a high frequency component removal may be suppressed.
