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.
