1. A sample-collecting device comprising:
an upper housing having a sample inlet formed in an upper surface thereof and a sample stopper formed on a lower surface thereof;
a lower housing coupled to the upper housing; and
a film part which is positioned between the upper housing and the lower housing and on which a sample input through the sample inlet is spread,
wherein the sample inlet is formed to have a pillar shape having a central passage,
the central passage is connected at a contact region of the sample inlet from an uppermost end to the lower surface of the upper housing, and
the sample stopper is a step formed on the lower surface of the upper housing, wherein the step is spaced a predetermined distance from a hole of the central passage, which is formed in the lower surface of the upper housing, to form a sample storage space, and the step comes into contact with the film part to seal a gap between the sample stopper and the film part so that the sample input into the sample storage space does not flow out between the sample stopper and the film part,
wherein
a diameter of the central passage is 0.7 mm;
a length of the central passage is 3.5 mm;
a step height of the sample stopper is 0.1 mm; and
the sample stopper is a step forming a circular sample storage space having a diameter of 1.5 mm.
