Abstract:
A core component is made of a sintered body of an inorganic powder, in which the core component includes a columnar winding portion and a flange portion integrally formed with the columnar winding portion at both axial ends of the winding portion, and a gap C, represented by the following Formula, between adjacent voids in the surface layer portion of the columnar winding portion, is 6 to 12 μm.
C=L−R Formula:
where, L is the average value of the distance between the centers of gravity between adjacent voids, and R is the average value of equivalent circle diameters of the voids.
C=L−R Formula:
where, L is the average value of the distance between the centers of gravity between adjacent voids, and R is the average value of equivalent circle diameters of the voids.
