| 主权项 | 1. A ferrite sintered body comprising a crystal grain of a Ni—Zn ferrite and a grain boundary thereof, wherein the ferrite contains silicon, and 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. | ||
