The invention provides an antenna coil and a method for manufacturing the same which are capable of realizing improvement of antenna properties and miniaturization. The antenna coil includes a core member (2 having an X-axis leg section (21) protruding in the X-axis direction from an intersection (2s) of the core member and having a Y-axis leg section (22) protruding in the Y-axis direction from the intersection, X-axis winding wires (5a, 5b) wound around the outer periphery of the X-axis leg section (21), and Y-axis winding wires (6a, 6b) wound around the outer periphery of the Y-axis leg section (22), at least one of an X-axis winding frame section (3) for the X-axis winding wire, the X-axis winding frame section being provided at the X-axis leg section (21), and a Y-axis winding frame section (4) for the Y-axis winding wire, the Y-axis winding frame section being provided at the Y-axis leg section (22), has one of intermediate flange sections (31, 41) for respectively separating the X-axis winding frame section and the Y-axis winding frame section into a pair of winding frame sections (4a, 4b) and a pair of winding frame sections (5a, 5b), the winding frame sections of each of the pairs corresponding to different winding shapes.
