PROBLEM TO BE SOLVED: To provide a method for manufacturing a microneedle array, which can close a needle-shaped recess with a chemical solution and has a high yield. A method for manufacturing a microneedle array is a mold having a first surface and a second surface facing each other and having a plurality of needle-shaped recesses on the first surface, and a discharge method for discharging a chemical solution in a first direction. An adjustment step of positioning and adjusting the nozzle, a relative movement step of relatively moving the mold and the discharge nozzle to match the position of the needle-shaped recess and the position of the discharge nozzle in a plan view in the first direction, and a discharge nozzle. The chemical solution is discharged from the needle-shaped recess toward the needle-shaped recess, and after the discharge step, the mold is vibrated to move the chemical solution toward the needle-shaped recess and close the needle-shaped recess with the chemical solution. It includes a vibration step and a suction step of sucking the second surface of the mold.
