MULTILAYER COIL COMPONENT
First Claim
1. A multilayer coil component, comprising:
- an element body;
a coil disposed in the element body;
an external electrode disposed on the element body;
a connection conductor including one end connected to the coil and another end connected to the external electrode, the connection conductor being disposed in the element body,wherein the element body includesa principal surface that is a mounting surface; and
an end surface positioned adjacent to the principal surface and extending in a direction crossing to the principal surface, andthe external electrode includesan underlying metal layer formed on the principal surface and the end surface; and
a conductive resin layer formed to cover the underlying metal layer,the other end of the connection conductor is exposed at the end surface and connected to the underlying metal layer, andwhen viewed from a direction orthogonal to the end surface, a position where the other end of the connection conductor is exposed at the end surface differs from a position where a thickness of a portion positioned above the end surface of the conductive resin layer is maximum.

Abstract
A multilayer coil component includes an element body, a coil disposed in the element body, and an external electrode disposed in the element body and electrically connected to the coil. The element body includes a principal surface that is a mounting surface, and an end surface positioned adjacent to the principal surface and extending in a direction crossing to the principal surface. The external electrode includes an underlying metal layer and a conductive resin layer. The underlying metal layer is formed on the principal surface and the end surface. The conductive resin layer is formed to cover the underlying metal layer. A thickness of the conductive resin layer at an end positioned above the principal surface of the underlying metal layer is equal to or greater than 50% of a maximum thickness of a portion positioned above the principal surface of the conductive resin layer.
