According to one embodiment of the present invention, a multiplex PCR device is disclosed. The multiplex PCR device comprises a multiplex PCR chip simultaneously carrying a plurality of mutually different nucleic acid molecules, and the invention may be characterised in that, attached spaced apart from each other on the multiplex PCR chip, there are a plurality of probes used for hybridization reactions whereby hybridization takes place specifically with mutually different amplified sequences of the nucleic acid molecules.
