Abstract: An apparatus for fabricating a microneedle includes a first substrate having a plurality of first spaced viscous materials formed on one side thereof and including at least one first transmission area, a second substrate disposed opposite to the first substrate, having a plurality of second spaced viscous materials formed on one side thereof facing the first substrate and including at least one second transmission area corresponding to the first transmission area, a light emitting unit arranged to correspond to the first transmission area on the other side of the first substrate and emitting light, and a light receiving unit arranged to correspond to the second transmission area on the other side of the second substrate. The microneedle manufacturing apparatus checks whether the first substrate and the second substrate are aligned according to whether the light receiving unit receives light emitted from the light emitting unit.
