摘要： A transdermal drug delivery patch according to an exemplary embodiment of the present invention includes: a flexible base layer; and a plurality of microneedle disposed at one surface of the base layer. Each of the plurality of microneedles includes a biodegradable polymer and a drug and has an empty space inside. Each of the plurality of microneedles is formed as a star-shaped pyramid including a plurality of protrusions extending in a radial direction, and a part between two protrusions adjacent along the circumferential direction among the plurality of protrusions is concave.
