1. A microcurrent patch comprising:
a base made of a polymer film;
a small-sized battery disposed on the base to generate current;
a circuit disposed on the base and connected to the small-sized battery, wherein the circuit are disposed in two regions so that the current flows in the circuit; and
a glue layer having one face disposed on the base and constructed to cover the small-sized battery and the circuit, and having the other face attached to a skin of a human body, wherein the glue layer has a plurality of holes defined therein overlapping the circuit and served as a passage to allow the current to flow between the skin and the circuit when the patch is attached to the skin of the human body,
wherein the circuit is electrically connected to the small-sized battery, the circuit is divided into a circuit portion connected to a positive terminal of the small-sized battery and a circuit portion connected to a negative terminal of the small-sized battery,
the circuit is formed in a linear shape and crosses each other in a net shape so that current flows smoothly over a large area of the skin, and
each of both opposing faces of the glue layer is made of acrylate and has insulation ability, and the glue layer has a thickness of 0.01 μm to 1,000 μm.
