Abstract
A pressed powder material according to embodiments is a pressed powder material including first magnetic metal particles having a first magnetic metal phase containing Fe and Co; and second magnetic metal particles having a second magnetic metal phase containing Fe, in which when the amounts of Co with respect to the total amounts of Fe and Co of the first and second magnetic metal particles are designated as Co1 and Co2, respectively, the ratio of Co2 to Co1 (Co2/Co1) is from 0 to 0.5, the average value of the ratio of the major axis to the minor axis is 2 or greater for the first magnetic metal particles and 1 or greater for the second magnetic metal particles, the second magnetic metal particles are present between the particles of the first magnetic metal particles, and the average value of the major axis of the second magnetic metal particles is equal to or longer than the average value of the major axis of the first magnetic metal particles.
