1. A composite coil pattern for wireless charging and magnetic security transmission (MST), the composite coil pattern comprising:
a wireless charging coil portion including a first terminal, a second terminal, and a coil connecting the first terminal to the second terminal; and
a magnetic security transmission (MST) pattern portion connected to the coil through a connection line branching from a curved outer periphery of the coil, wherein:
the MST pattern portion is at one side in a direction with respect to the coil,
the MST pattern portion extends in a zig zag shape and includes a plurality of lines which extend parallel to the direction,
a first portion of the plurality of lines comprises inner ends located close to the coil and arranged to correspond to the curved outer periphery of the coil, and outer ends located far from the coil,
a second portion of the plurality of lines, adjacent to the first portion of the plurality of lines, comprises inner ends located close to the connection line and arranged to correspond to the connection line and outer ends located far from the connection line,
an inner end of a first line from among the plurality of lines and an inner end of a second line next to the first line are connected to each other, and an outer end of the second line and an outer end of a third line next to the second line are connected to each other, so that the plurality of lines are connected in series,
the inner ends and the outer ends of the plurality of lines are bent to be connected to adjacent parallel lines of the plurality of lines,
the inner ends of the first portion of the plurality of lines are bent along the curved outer periphery of the coil, and
the inner ends of the second portion of the plurality of lines are bent along the connection line.
