Abstract:
This method for manufacturing an antenna device (100) includes a melting step and a removal step. The antenna device (100) comprises: an antenna section (20) on which is wound a coil wire (40) having a coil core (47) covered by an insulation film (46); and a base (30) having a pad section (331) for which a portion of the coil wire (40) is soldered using a brazing filler material (50). In the melting step, a laser is radiated on the brazing filler material (50) supplied onto the pad section (331), melting the brazing filler material (50). In the removal step, the coil wire (40) is immersed in the melted brazing filler material (50) and a portion of the insulation film (46) is removed from the coil wire (40), and the coil wire (40) and the pad section (331) are joined by the brazing filler material (50).
