Abstract
An antenna coil includes: a core (3) formed by shaping a magnetic material into a bar-like configuration; a bobbin (1) having a through-hole (12) into which the core (3) is to be inserted; a connection section (15) fixed to the bobbin (1) so as to extend in a length direction of the core (3) from the bobbin (1), with the core (3) inserted into the through-hole (12); a winding (14) which is wound around the bobbin (1) and whose ends are connected to the connection section (15); and a connector terminal (25) which is provided at a certain position in the length direction of the core (3), which fixes the connection section (15) in position, and which determines the position of the winding (14) in the length direction of the core (3).
