A portable terminal includes a non-conductive resin chassis that is formed by molding a molding material and internally provided with a printed circuit board on which a wireless circuit is formed, and an antenna pattern that is disposed on a wall surface of the chassis and in a region excluding a eject pin track formed when the chassis electrically connected with the printed circuit board is formed, wherein the antenna pattern is constituted by sequentially laminating a copper layer, a nickel layer and a gold layer by electroless plating, and the nickel layer is rendered amorphous. |
