Abstract

This method for manufacturing a powder core is provided with: a step for heat-treating amorphous soft magnetic alloy powder to obtain nanocrystal powder; a step for obtaining granulated powder from nanocrystal powder, malleable powder, and a binder; a step for pressure-molding the granulated powder to obtain a green compact; a step for curing the binder by heat-treating the green compact at a temperature which is equal to or higher than the curing initiation temperature of the binder and lower than the crystallization initiation temperature of the amorphous soft magnetic alloy powder.
