From Wikipedia:
In metals, which make up the wires and other conductors in most
electrical circuits, the positive charges are immobile, and the charge carriers are
electrons. Because the electron carries negative charge, the
electron motion in a metal conductor is in the direction opposite to that of conventional (or
electric) current.
