(57) In an antenna coil which includes a core member having an X-axis leg section protruding
in the X-axis direction from an intersection of the core member and having a Y-axis
leg section protruding in the Y-axis direction from the intersection, X-axis winding
wires wound around the outer periphery of the X-axis leg section, and Y-axis winding
wires wound around the outer periphery of the Y-axis leg section, at least one of
an X-axis winding frame section for the X-axis winding wire, the X-axis winding frame
section being provided at the X-axis leg section, and a Y-axis winding frame section
for the Y-axis winding wire, the Y-axis winding frame section being provided at the
Y-axis leg section, has one of intermediate flange sections for respectively separating
the X-axis winding frame section and the Y-axis winding frame section into a pair
of winding frame sections and a pair of winding frame sections, the winding frame
sections of each of the pairs corresponding to different winding shapes.
