Claim:
A sample-harvesting sheet for harvesting an inspection sample for threat detection from a sample-harvesting portion of an inspection object by rubbing or wiping the sample-harvesting portion, wherein the sample-harvesting sheet has a single layer structure and two perforated lines formed in a plane of the sample-harvesting sheet, each of the two perforated lines being formed of a plurality of perforated line recesses, the recesses being formed by punching and arranging in a linear state, and the two perforated lines being crossed each other at a single point and at right angles, the crossing position of the two perforated lines being situated at a center of the sample-harvesting sheet, and wherein, when the sample-harvesting sheet moves and rubs or wipes the sample-harvesting portion of the inspection object without restricting the sheet direction or the sheet moving direction while in contact with the sample-harvesting portion of the inspection object, the perforated line recesses catch the inspection sample deposited on the sample-harvesting portion of the inspection object and transfer the inspection sample from the sample-harvesting portion of the inspection object to the plane of the sample-harvesting sheet and retain therein, and the sample-harvesting sheet together with the retained inspection sample being charged into a threat detection unit for analysis of the inspection sample.
