To provide a manufacturing method of an antenna capable of inserting a plurality of antenna elements into a correct position.
A first antenna element 3 is put into a groove 22 of a support member 2, and the first antenna element 3 is laid at the bottom of the groove 22. An insulation sheet 4 is put into the groove 22, and the insulation sheet 4 is overlapped on a part of the first antenna element 3. A second antenna element 5 is put into the groove 22, and a part of the second antenna element 5 is overlapped on the insulation sheet 4. A pressing member 6 is inserted into the groove 22; and the first antenna element 3, the insulation sheet 4, and the second antenna element 5 are secured temporarily to the support member 2. The support member 2 is set in a metal mold, and then molten resin is poured into the metal mold. The pressing member 6, the second antenna element 5, the insulation sheet 4, the first antenna element 3, and the support member 2 are wrapped by the poured-in molten resin. A coating resin 7 is obtained after the molten resin solidifies.
