Method of manufacturing coil antenna and method of manufacturing coil antenna package

A method of manufacturing a coil antenna package, the coil antenna package including a coil antenna that includes a coil antenna body and a coil wire wound around the coil antenna body;

• and a mounting base on which the coil antenna is surface-mounted, the method comprising:
• stacking a flexible board on a flexible magnetic material to form a laminate;
• dividing the laminate to form the coil antenna body;
• winding the coil wire around the coil antenna body;
• temporarily fixing a terminal end of the coil wire to the coil antenna body;
• performing treatment on a part of the coil wire that comes into contact with a connection part of the mounting base, so that the coil antenna is electrically connectable to the mounting base;
• and
• disposing the coil antenna on the mounting base so that the part of the coil wire comes into contact with the connection part, and joining the coil antenna to the mounting base with solder flow.
