Microneedle patch and production method therefor

A method of manufacturing a micro-needle patch, the method comprising:

• forming a support inserted into a receiving portion in a tray, the support having a first surface and a second surface opposite the first surface, wherein the support includes:
• a plurality of supports each inserted into the receiving portion in the tray;
• forming a plurality of micro-needles projecting from the first surface of the support;
• forming a first passage from the support to each of the plurality of micro-needles or a second passage from the support between two neighboring micro-needles;
• forming a groove in the second surface of the support,
• electrospraying a spraying solution into the groove to form droplets, the spraying solution comprising a transmitter to be transferred, a biodegradable resin, and a solvent;
• accumulating the droplets in the groove to form a gel membrane for delivery of the transmitter to be transferred,
• adhering a first protective film on the gel membrane to protect the gel membrane;
• and
• adhering a second protective film on the first surface of the support to cover the micro-needles.
