    摘要: A laminated coil component includes a magnetic body part made of a ferrite material and a coil conductor wound into a coil shape and embedded in the magnetic body part to form a component base. The component base is divided into a first region near the coil conductor and a second region other than the first region. The grain size ratio of the average crystal grain size of the magnetic body part in the first region to the average crystal grain size of the magnetic body part in the second region is 0.9 or less. The molar content of CuO in the ferrite raw material is set to 0.2 to 4 mol %. In a method laminated coil component, the coil is formed from a conductive paste including Ag, and firing the laminated body is performed by setting the oxygen concentration is 0.1 volume % or less as a firing atmosphere.
