PROBLEM TO BE SOLVED: To provide a microneedle patch rapidly absorbed into a body and method of using the same.SOLUTION: In the rapidly dissolving method for a microneedle array, void holes are set in an adhesive tape adhered on the back of the microneedle array, moisture is supplied from the back face of the microneedle array, and the microneedle array is rapidly swelled and dissolved. Thus the constituent of the microneedle is rapidly absorbed into a body. For the purpose of supplying moisture, a gauze containing a lotion or cosmetic solution, nonwoven fabric or tape, or an aqueous gel pack can be used. The time for dissolving the microneedle which has required 1 to 3 hours in conventional methods can be shortened to 10-30 minutes.
