A coil component has a first surface and a second surface facing each other. The coil component has a coil conductor formed into a spiral shape, an insulating resin layer covering the coil conductor, a magnetic resin layer disposed on the first surface side of the insulating resin layer without being disposed on the second surface side of the insulating resin layer, and an external terminal disposed at least on one surface on the first surface side of the magnetic resin layer and electrically connected to the coil conductor. The magnetic resin layer is made of a composite material of a resin and a metal magnetic powder. The external terminal includes a metal film contacting the resin and the metal magnetic powder of the magnetic resin layer.

A paper sheet handling apparatus includes a stacking unit which allows paper sheets transported by a transport unit to be stacked therein in alignment with faces of an adjacent pair of the paper sheets being in contact with each other. A recognition unit recognizes which of a face or back of each of the paper sheets transported faces up, and how each of the paper sheets is oriented. A controller classifies the paper sheets into a plurality of types different in thickness distribution based on the result of recognition, manages the number of paper sheets of each type stacked in the stacking unit, and makes a determination whether to permit the stacking of the paper sheets in the stacking unit based on the type of the paper sheets recognized by the recognition unit, and the number of paper sheets of each type that have been stacked in the stacking unit.
