Abstract: The present invention provides a manufacturing method of a microneedle biosensor including a support layer including a) a step of forming a mold by forming grooves corresponding to shapes of microneedles of a working electrode, a counter electrode, and a reference electrode in a solid resin block; b) a step of imprinting the working electrode, the counter electrode, and the reference electrode using acryl or PLA on the mold; c) a step of forming a support layer by coating an epoxy- or urethane-based photo-curable adhesion after performing the step b); d) a step of forming a metal layer by forming shadow masks corresponding to patterns of the working electrode, the counter electrode, and the reference electrode and sputtering an Au or Au+Ti/Cr adhesive layer, after performing the step c); and e) forming a passivation layer on the metal layer.
