摘要： A multilayer coil component is provided to have high reliability and in which internal stress arising from the difference in firing shrinkage behavior and/or thermal expansion coefficient between ferrite layers and internal conductor layers is alleviated without forming conventional voids between the ferrite layers and the internal conductor layers. A method of manufacturing a multilayer coil includes a step of isolating interfaces between internal conductors and surrounding ferrite by allowing a complexing agent solution to reach interfaces between the internal conductors and the surrounding ferrite through side gap portions from side surfaces of a ferrite element including a helical coil. The complexing agent solution contains at least one selected from the group consisting of an aminocarboxylic acid, a salt of the aminocarboxylic acid, an oxycarboxylic acid, a salt of the oxycarboxylic acid, an amine, phosphoric acid, a salt of phosphoric acid, and a lactone compound.
