る。゛ The present invention relates to a gas sensor and a method of manufacturing a gas permeable membrane for a biosenna using the same. There is a demand for miniaturization of biosensors, and gas sensors must also be miniaturized. As parts become smaller as a result, structures and manufacturing methods that are easy to assemble even when the size becomes smaller are required.

プの熱融着によシ作製する。Conventional biosennas use a film-like gas-permeable membrane, which is attached manually. As biosensors have become more compact, gas permeable membranes have also become smaller pieces, making them difficult to handle and requiring only experienced personnel to assemble them. In order to make membrane parts, a ring with gas permeable membrane tFEP (Fluorinated Eth)

ダメージを受けるのを紡ぐことができる。The ring with a gas permeable membrane of the present invention can completely adhere the O-ring and the gas permeable membrane by utilizing the fact that FEPs can be thermally fused together. In addition, by modifying the shape and surface of the hot plate, it is possible to prevent the thin FEP film from being damaged by heat.

- Place the film 2 on the plate 1, press it against the hot plate 3, and heat it for 11 g. At this time, the temperature of the hot plate 3 is controlled at 250 to 260°C, and the hole 4 is shaped to match the inner diameter of the chip L as shown in the first diagram.If the 0 temperature is too high, If the film 2 is melted and the hole is <0, the shape of the hot plate 3 is flat.
The film 2 comes into direct contact with the hot plate 3 and melts, creating holes. Furthermore, the surface of the hot plate 30 is coated with dimethyldichlorocycne ((CHsbCjt
