1. An electronic component, comprising:
a magnetic core member that is made of a magnetic material and that has a flat base and a core, the flat base having a top surface, a bottom surface, a first side surface, and a second side surface opposite to the first side surface, the core being located on the top surface of the flat base;
a winding that has an edgewise coil in which the core is inserted, the edgewise coil being formed by winding a flat wire having first and second ends opposite to each other, the winding having first and second non-wound flat wires that extend from the edgewise coil, the first and second non-wound flat wires including the first and second ends, respectively;
first and second belt-shaped electrodes that are along the first side surface, the bottom surface, and the second side surface of the flat base, the first and second belt-shaped electrodes being formed separately from the edgewise coil; and
a magnetic exterior body that covers at least the core and the edgewise coil,
wherein a first end portion of the first belt-shaped electrode upwardly extends beyond the top surface of the flat base and is bent toward the edgewise coil, and a first tip of the first end portion is aligned over the top surface of the flat base in a plan view,
a second end portion of the second belt-shaped electrode upwardly extends beyond the top surface of the flat base and is bent toward the edgewise coil, and a second tip of the second end portion is aligned over the top surface of the flat base in the plan view, and
the first and second ends of the first and second non-wound flat wires are electrically connected to the first and second tips of the first and second belt-shaped electrodes, respectively.
