  • Patent number: 11107623
    Abstract: An inductor includes a coil including a winding portion and a lead-out portion, a body constituted by a magnetic member and enclosing the coil, a protection layer disposed on a surface of the body, and an outer electrode. The body has a bottom surface, a top surface, two end surfaces, two side surfaces, and first and second R-chamfered sections. The outer electrode includes first and second electrode regions. The first electrode region is located on the bottom surface and is electrically connected to the lead-out portion. The second electrode region is located on the protection layer on each end surface. The radius of curvature of the first R-chamfered section in a cross section perpendicular to the bottom surface and the end surfaces is smaller than that of the second R-chamfered section in a cross section perpendicular to the end surfaces and the side surfaces.

The body has a bottom surface, a top surface, two end surfaces, two side surfaces, and first and second R-chamfered sections. The outer electrode includes first and second electrode regions. The first electrode region is located on the bottom surface and is electrically connected to the lead-out portion. The second electrode region is located on the protection layer on each end surface. The surface roughness of part of the bottom surface where the first electrode region is disposed is greater than that of the protection layer on each of the end surfaces where the second electrode region is disposed.

The first electrode region is located on the bottom surface and is electrically connected to the lead-out portion. The second electrode region is located on the protection layer on each end surface. The number of conductive particles in the first electrode region intersecting with a unit length of a straight line perpendicular to the bottom surface is greater than that in the second electrode region intersecting with a unit length of a straight line perpendicular to the end surface.
