PROBLEM TO BE SOLVED: To provide a sampled liquid storage device with a simple configuration, capable of easily storing a sufficient amount of living body composition liquid in a short period of time.SOLUTION: The sampled liquid storage device includes: a base body part 11 and a puncturing part 13 for performing puncturing to a living body which is projected from the base body 11 and integrally formed with the base body. The puncturing part 13 includes a sampled liquid flow passage 17. The base body part 11 includes a storage flow passage 15 communicating with the sampled liquid flow passage 17. The living body constituent liquid sampled in the sampled liquid flow passage 17 is stored in the storage flow passage 15 after being transferred by capillarity. The storage flow passage 15 has curved or branched parts with shapes for transferring the living body composition liquid by capillarity. At least, the deepest part 36 most separated from the sampled liquid flow passage 17 is opened to atmosphere.COPYRIGHT: (C)2009,JPO&INPIT【課題】十分な量の生体組成液を短い時間で収容し易く、しかも、構成が簡単な採液収容装置を提供する。【解決手段】基体部11とこの基体部11から突出した生体への穿刺部13とが一体に設けられ、穿刺部13には採液流路17が設けられると共に、基体部11には採液流路17と連通した収容流路15が設けられ、採液流路17で採液された生体組成液が毛細管現象により収容流路15に移送されて収容されるように構成されていて、収容流路15が、生体組成液を毛細管現象により移送可能な形状を有する曲部又は分岐部を備えて構成され、少なくとも採液流路15から最も離間した最奥部36が大気に開放されている。【選択図】 図1
