Abstract
In a multilayer coil component, an end of a lower coil layer and an end of a connecting part are directly overlapped, and the end of the lower coil layer includes a contact edge positioned on a side of the connecting part and being in contact with the connecting part and a non-contact edge positioned on a side opposite to the connecting part and not being in contact with the connecting part. Then, the contact edge and the non-contact edge are not overlapped when viewed from a laminated direction. Consequently, a propagation distance of a crack becomes longer as compared with the case where an end face is parallel to the laminated direction, effectively suppressing advance of the crack. Suppressed advance of a crack in this manner makes the multilayer coil component provide a high component strength as a whole.
