A ferrite sintered body contains Fe, Mn, Zn, Cu, and Ni. Supposing that Fe, Mn, Zn, Cu, and Ni are converted into FeO, MnO, ZnO, CuO, and NiO, respectively, and the sum of the contents of FeO, MnO, ZnO, CuO, and NiO is 100 mol %, the sum of the contents of FeOand MnOis 48.47 mol % to 49.93 mol %, the content of MnOis 0.07 mol % to 0.37 mol %, the content of ZnO is 28.95 mol % to 33.50 mol %, and the content of CuO is 2.98 mol % to 6.05 mol %. Furthermore, 102 ppm to 4,010 ppm Zr in terms of ZrOand 10 ppm to 220 ppm Al in terms of AlOare contained per 100 parts by weight of the sum of the amounts of contained FeO, MnO, ZnO, CuO, and NiO.
