Abstract:
A method for manufacturing an inductor element for noise suppression, comprising the steps of:treating iron particles with phosphoric acid;forming a paste comprising the treated iron particles and resin;coating one surface of a supporting body with the paste so as to form a sheet;forming a conductive line by printing a conductive paste on said sheet;coating said conductive line with the paste comprising the treated iron particles and resin so as to cover said conductive line and form a core;forming two terminal conductors on opposite ends of said core; andapplying heat treatment under pressure,wherein said iron particles have diameters that fall within a range of 0.1 .mu.m to 10 .mu.m,a content of said iron particles is within a range of 40 vol % to 63 vol %, anda weight ratio between said iron particles and said phosphoric acid is approximately 1000:5.
