問題がある。However, in the above conventional space drifting object capturing apparatus, the foil 1 is formed by sandwiching the aluminum foil or the copper foil between the holding bodies 2 made of a flexible material. Therefore, when aluminum foil is used, since aluminum is weak against acid and easily deteriorated by acid, it is necessary to pay attention to the assembly and disassembly work performed in the atmospheric environment, and the durability of the trapping device is a problem. There is.

, Is the main component of orbital dust-sized drifting substances, and often captures the debris of such alumina particles, but in the case of a capture device using aluminum foil,
When capturing the debris of alumina particles, it is difficult to distinguish the debris from the aluminum foil fragments or debris.
In addition, when the captured space drifting object is used as a sample for analysis by an instrument analyzer, the captured object cannot be analyzed while it remains on the aluminum foil, so the captured object is peeled off from the aluminum foil. It is necessary to transfer it to a gold pedestal, etc., which may damage or contaminate the captured space drifting objects.

る、という問題がある。When copper is used instead of aluminum for the foil 1 of the above conventional trapping device, when debris of alumina particles are trapped, the debris of alumina particles can be distinguished, so that separation is easy. Since copper is sensitive to moisture and easily rusts, as in the case of aluminum foil, attention must be paid to the assembly and disassembly work performed in the atmospheric environment, and the captured substance on the copper foil should be analyzed by an instrument analyzer. However, there is a problem that it is necessary to transfer the catch from the copper foil to a gold pedestal or the like.

Moreover, as a result of repeated efforts and research to obtain something that can be analyzed with an instrument analyzer while the captured matter is placed on the foil, it is sufficient to use gold that has not been considered at all as a foil. Then, the present invention was made.

Since each gold foil is adhered or vapor-deposited to the holding body and fixed, and is housed in a case with an open upper surface, even when the debris of alumina particles, which has been increasing in recent years, is captured, the debris of the alumina particles is also captured. Can be clearly distinguished, and the debris captured on the gold foil can be analyzed with an instrument analyzer while being attached to the gold foil without transferring it to another. It is possible to prevent damage and contamination of catches that may be caused by peeling from the foil,
In addition, the gold foil has an excellent effect that it is less likely to be deteriorated by acid and moisture and has excellent durability as compared with the aluminum foil and the copper foil.
