Localizing the adhesion place of the blood in after the using, even with when the blood is made to take in from the skin which makes handling easy, making the skin the stab device keep and the like which the stab is done, the stab it does, the retention territory to which the soiling does not come in contact increasing, the blood analysis element which enlarges degree of freedom of handling. Blood analysis element A opens the blood-collecting mouth which takes in the blood (4) and the bleeder (5) alienating phase (1a) with, respectively, inside the blood-collecting mouth (4) and the bleeder (5) the passage section which is made to communicate the plate shaped element itself which it possesses (6) (100) with, the passage section (6) distribution facilities is done inside, through the blood-collecting mouth, the blood analysis section which analyzes the blood which (4) is taken in (7) with possesses.使用後における血液の付着箇所を局所化して取り扱いを容易にし、皮膚を穿刺する穿刺装置等に保持させて、穿刺した皮膚から血液を取り込ませる場合でも、汚れが付着しない保持領域が増加されて取り扱いの自由度を大きくした血液分析素子。血液分析素子Aは、血液を取り込む採血口(4)及び通気口(5)が一面(1a)で離間してそれぞれ開口し、内部に採血口(4)と通気口(5)とを連通させる通路部(6)を有する板状の素子本体(100)と、通路部(6)内に配設され、採血口(4)を介して取り込まれた血液を分析する血液分析部(7)とを有する。
