A micro-needle patch has microneedles extending from a first main surface, which is made of a material including chitin and/or chitosan. The micro-needle patch has a feed substance on at least one of the first main surface and a second main surface. The micro-needle patch makes insertion of the microneedles into a living body easier. The micro-needle patch is manufactured by pressing a plate having a recessed pattern on a surface thereof, the recessed pattern including recesses corresponding to micro-needles of at least one micro-needle patch, against a sheet or film of a raw material to form protrusions corresponding to the recesses on a surface of the sheet or film.
