Disclosed is a glass particle that can produce a soft magnetic composite material with low eddy current loss and high strength. Glass particles soft magnetic composites, for example, represented by mass% based on oxide, SiO 2 and B 2 O 3 the total more than 10%, B 2 O 3 less than 25%, containing 40 to 65% of ZnO And has an average particle size of 1 to 500 nm. |
