1. A microcoil element, comprising:
a wiring layer having continuous multiple metal line segments that is formed of multiple loops of continuous multiple metal line segments around a starting point, and every metal line segment including a first electrode end and a second electrode end, wherein the starting point is a first electrode of the microcoil element, and an end of the continuous multiple metal line segments is a second electrode of the microcoil element; and
at least one first electrode zone and at least one second electrode zone, wherein the at least one first electrode zone is used to converge the first electrode ends of the multiple metal line segments and the first electrode end of every metal line segment on the wiring layer is leaded to the at least one first electrode zone via multiple metal lines; and the at least one second electrode zone is used to converge the second electrode ends of the multiple metal line segments and the second electrode end of every metal line segment is leaded to the at least one second electrode zone via multiple metal lines.
