Abstract: A device for interstitial fluid extraction, having a base material formed from a synthetic resin film, a pressure sensitive adhesive layer, a hydrogel layer formed from at least one hydrophilic polymer selected from the group consisting of polyvinyl alcohol and polyvinyl pyrrolidone, and a release layer, wherein the hydrogel layer has an area of a size that the pressure sensitive adhesive layer is exposed from around the hydrogel layer, does substantially not contain a sodium ion and causes no water separation.

Abstract: A interstitial fluid collection kit for collecting interstitial fluid extracted via micropores formed in a skin is disclosed. The kit includes a marker sheet that has an adhesive face and that defines a region in which micropores are to be formed; a transparent retention sheet having an adhesive face; and a collecting body that is retained by a part of the adhesive face of the retention sheet and that collects interstitial fluid extracted from the skin.

Abstract: A body fluid collection device for collecting body fluid through the skin, comprising: a sheet-like substrate provided with an adhesive surface; a first collection body for collecting body fluid, provided on the adhesive surface; a first detachable sheet which is detachably adhered on the adhesive surface so as to cover the first collection body; and a second detachable sheet which is detachably adhered on the adhesive surface, wherein one end of the second detachable sheet in a predetermined direction is overlaid on the far end of the first detachable sheet in the predetermined direction, and part of the far end of the first detachable sheet is separated from the adhesive surface in a non-adhered state is disclosed.
