PROBLEM TO BE SOLVED: To provide a laminated ferrite part, equipped with a hexagonal ferrite magnetic layer having a Z-phase as a primary phase. SOLUTION: Magnetic ferrite layers 2 and internal electrodes 3 are laminated alternately, and the internal electrodes 3 and has an outer electrodes 5 electrically connected to the internal electrodes 3 are provided to the laminate for the formation of a laminated chip bead 1. According to X-ray diffraction, the magnetic ferrite layer 2 is constituted of a magnetic hexagonal ferrite sintered body, that has a Z-phase (M3Me2Fe24O41: M is one or more from among alkaline earth metal elements, Me is one or more from among Co, Ni, Mn, Zn, Mg and Cu) as a primary phase and is 1 to 5 μm in average crystal grain diameter. |
