摘要:
A layered coil component includes a coil that is constructed by layering coil conductor patterns and ceramic sheets. The ceramic sheets include a first ceramic sheet and a third ceramic sheet having a permeability lower than the permeability of the first ceramic sheet. The third ceramic sheet has an arrangement that is astride at least two of the coil conductor patterns adjacent to each other in a layering direction, in a section including a coil axis of the coil. As a result, DC bias characteristics of the open magnetic circuit type layered coil component are improved.
