PROBLEM TO BE SOLVED: To provide a laminated coil component that has a side-winding structure that improves an impedance characteristic in a high frequency band and internal stress is relaxed while the strength is maintained.SOLUTION: In a laminated coil component that includes a magnetic portion that is sintered ferrite including Fe, Ni, Zn, and Cu, a coil-like conductor part that is formed so as to be buried in the magnetic portion, and a pair of external electrodes that are provided on the surface of the magnetic portion so as to be opposite to the coil center axis are electrically connected to both sides of the conductor part, the conductor part is constituted of a conductor including silver, and a particle diameter ratio of an average crystal grain diameter of a conductor part neighboring region of the magnetic portion to an average crystal grain diameter of the central region of the magnetic portion is 0.8 or less. |
