A coil material (1) includes on the same flat surface three annular sections (1a, 1b, 1c) that have a missing part and have substantially the same shape and size; a connection section (1d) which connects each one end of the annular sections (1a, 1b); and a connection section (1e) which connects the other end of the annular sections (1b) and one end of the annular sections (1c). Further, the coil material (1) has the three consecutive annular sections (1a, 1b. 1c) arranged in an L-shape. In a coil that was manufactured with the coil material (1), the connection section (1d) is bent substantially at the center between the annular sections (1a, 1b) that are connected by the connection section (1d) and the connection section (1e) is bent substantially at the center between the annular sections (1b, 1c) that are connected by the connection section (1e) so that the annular sections (1a, 1b, 1c) overlap coaxially leaving a space therebetween. |
