PROBLEM TO BE SOLVED: To provide a level wound coil in which a coil (tube) is hardly damaged, folded or deformed, and the coil is hardly collapsed when uncoiling the coil. SOLUTION: In the level wound coil 1, a tube 2 is multiply and regularly wound in a coil, and arranged on a plate 8 so that its axial direction is directed to the vertical direction, and an end of the tube 2 of an innermost layer coil 3 is drawn to uncoil the level wound coil. A tube end portion 6a on an outermost layer coil 6 side is arranged below the outermost layer coil 6 to support the outermost layer coil 6. In the level wound coil, damages, bend or deformation generated on the tube 2 at a lower portion of the n-1 th layer coil 5 when uncoiling the innermost layer coil 3 is prevented, and collapse of the n-th layer coil 6 generated when uncoiling the n-1 th layer coil can be prevented.
