Abstract: The present invention relates to a dissolvable microneedle comprising needles made of a water-soluble material assembled on one side of a base, which is a sheet material having liquid-permeable cavities, wherein the needles being assembled to the base such that bottom portion of the needles is directly connected to the base, the connection of the bottom portion of the needle s to the base forming through a structure in which the bottom portion of the needles penetrates into the base (102), occupying some or all cavities of the base. The dissolvable microneedle with the structure according to the present invention is convenient to use as the penetrating structure that connects the needle s to the base can be dissolved quickly and efficiently; therefore, the base can be removed from the top skin without the needles embedded within the skin being pulled out.
