A transmission line includes a conductor for signal transmission and an isolating layer covering the conductor. The isolating layer includes a first isolating strand group and a second isolating strand group. The first isolating strand group is wound in a way that forms an S-twist around the conductor along an axis direction the conductor, and the second isolating strand group is wound in a way that forms a Z-twist around the conductor along the axis direction. In an interval from a first position to a second position, including the first position, the first isolating strand group continuously overlaps an outside of the second isolating strand group, and in an interval from the second position to a third position, including the second position, the second isolating strand group continuously overlaps an outside of the first isolating strand group.
