1. A common-mode choke coil comprising:
a core that includes a winding core portion, a plate core, and a pair of flange portions formed at ends of the winding core portion;
electrodes that are included on a side of the pair of flange portions that is opposite to the plate core; and
first and second wires that are wound around the winding core portion and that include extended portions electrically connected to the electrodes on the side of the pair of flange portions that is opposite to the plate core, wherein
the flange portions are continuous with the winding core portion and have slopes each of which guides a specific one of the extended portions to a specific one of the electrodes,
the side of the pair of flange portions that is opposite to the plate core includes a pair of mounting surfaces that are spaced apart from each other and a pair of outer recesses that are spaced apart from each other with the pair of mounting surfaces therebetween, the outer recesses each being adjacent to a respective mounting surface,
the mounting surfaces project further in a heightwise direction relative to the plate core than the outer recesses,
each electrode extends from one of the mounting surfaces to the adjacent outer recess, and
each specific extended portion of the first and second wires is attached to each respective specific electrode at the respective outer recess.
