The thermocycling inspection device includes a holder-accommodating spacefor accommodating the chip holdertherein, a thermocycling sectionfor heating and cooling the inspection chip, and a detectorfor taking a picture of the inspection chip, and when the thermocycling sectionheats or cools or when a picture is taken by the detector, the thermocycling sectionis disposed on one side of the holder-accommodating space, the detectoris disposed on other side of the holder-accommodating space, and the holder-accommodating spaceis formed such that an optical axis of the detectorand a sample introducing portmatch with each other. According to this, polymerase chain reaction can be carried out, and inspection can be carried out using the inspection chip which carries out the polymerase chain reaction.
