Level wound coil, method of manufacturing same, and package for same

A level wound coil (LWC), comprising:

• a plurality of coil layers, each of which comprises a pipe wound in alignment winding and in traverse winding, wherein a coil of a (m+1)-th coil layer is located such that a pipe at a start position thereof is fitted into a concave part formed outside of the m-th coil layer and between a pipe at a lower end of the m-th coil layer and an adjacent pipe of the m-th coil layer, wherein, when the LWC is disposed on a mount surface perpendicular to a coil center axis of the LWC, m is an odd natural number if a start position of the winding of the LWC is located at an upper end of the coil and m is an even natural number if the start position of the winding is located at a lower end of the coil,
• wherein the LWC comprises a shift section such that the pipe is shifted from the m-th coil layer to the (m+1)-th coil layer on a bottom surface thereof when the LWC is disposed on the mount surface, and
• wherein the shift section comprises a k-th shift section on an inner layer and a (k+1)-th shift section on an outer layer side, wherein a start point of the (k+1)-th shift section does not transit, relative to a start point of the k-th shift section, to a winding direction of the pipe.
