PURPOSE: A smart card is provided to simplify a manufacturing process of a loop type antenna used in a contactless smart card and enhance an induction voltage induced by the antenna. CONSTITUTION: The device comprises a ground pad(30), a communication pad(40) and an antenna coil(70). The pads(30,40) transmits the voltage, induced by the signal which an antenna(20) receives from a reader, to a chip. The pads(30,40), bonded to the chip, transmits the current of the antenna coil(70). The antenna coils(70) are in parallel connected between the ground pad(30) and the communication pad(40). The surface of the antenna coils(70) are on the same plane with the pads(30,40).
