Abstract
To reduce connection resistance in a two-terminal type coil component with a single coil conductor incorporated in an element body.SOLUTION: A coil component 100 comprises: a coil conductor embedded in an element body 110; a bump conductor 131 which is connected to one end of the coil conductor, and is exposed to a mounting surface S0 and side surfaces S1 and S3; a bump conductor 132 exposed to the mounting surface S0 and side surfaces S2 and S3; a dummy bump conductor 141 exposed to the mounting surface S0 and side surfaces S1 and S4; a dummy bump conductor 142 exposed to the mounting surface S0 and side surfaces S2 and S4; a conductive resin layer 121 connecting between the bump conductor 131 and the dummy bump conductor 141; and a conductive resin layer 122 connecting between the bump conductor 132 and the dummy bump conductor 142. At least a part of a side surface portion of the bump conductors 131 and 132 is not covered with the conductive resin layers 121 and 122, and thus, a connection resistance of this portion is reduced.SELECTED DRAWING: Figure 1
