The purpose of the present invention is to provide an instrument with which it is possible to collect a minute quantity of a specimen in a state suitable for later testing, without the need for an absorbent or chemical solution, even when a specimen of minute quantity is being collected. A further purpose is to provide an instrument with which it is possible to collect blood suitable for later blood testing, even when the sample is a minute quantity of peripheral blood instead of brachial vein blood. Yet a further purpose is to provide a minute specimen collection and separation instrument for use in measuring a sample of a minute quantity of peripheral blood with good accuracy using a conventional reagent and analysis device. Provided is a specimen collection and separation instrument equipped with: a specimen collection instrument having a specimen collection unit that uses capillary action； and an analyte storage tool having a housing means into which the specimen collection instrument is insertable, whereby the specimen collection instrument containing the collected specimen is integrated by means of insertion, so as to permit centrifugal separation and storage or transport of the specimen, and the specimen of interest can be recovered following centrifugal separation.
