PROBLEM TO BE SOLVED: To provide a plastic substrate for microchips having a saturated cyclic polyolefin resin in which the fluorescence of the substrate is suppressed that increases by applying oxidation treatment to the plastic substrate for microchips made of a norbornene resin having the saturated cyclic polyolefin resin. SOLUTION: The substrate is brought into contact with water molecules (for example, immersed in pure water) to introduce a hydroxy group into a carbon atom in a radical state, immediately after the substrate is subjected to the oxidation treatment (for example, oxygen gas low temperature plasma discharge). Consequently, the ratio of the carbon atom having aπ-bond in a molecular layer on the surface of the substrate decreases to less than that for the state of only oxidation treatment.
