The purpose of the present invention is to provide a sintered ferrite body having high strength without a special coating layer causing an increase in cost; an electronic component having excellent strength using the sintered ferrite body; and a power supply device having high reliability using the electronic component. According to the present invention, the sintered ferrite body is used for an electronic component such as a transformer or a choke coil, wherein a third of the sintered ferrite body thickness from the outermost surface to the inner side is compressively deformed. |
