Abstract:
A ferrite sintered body includes a crystal grain of a Ni—Zn ferrite and a grain boundary thereof, in which Ti is unevenly distributed in an outer region of the crystal grain, the outer region extending from an interface of the crystal grain to a length of 20% of a major axis of the crystal grain.
