Abstract
A level wound coil (LWC) having a plurality of coil layers each of which has a pipe wound in alignment winding and in traverse winding. The LWC has a shift section where 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 a mount surface. The shift section has the k-th shift section on inner layer side and the (k+1)-th shift section on outer layer side, where 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.
