It is possible to provide a blood test device which does not pollute the puncture with respect to the disposal of blood sensor. Blood test device (11), and a puncture made on the holder and (13a) the lower holder from and (13b) and (13), the connector (18), the puncturing operation, the connector on the holder and (18) (13a) holds the lower holder and (13b) is across the sensor (24), and the sensor during discharge as well as rotate away the upper holder from (13a), the lower holder (13b), the said pivoting lower holder (13b exposing (24) the sensor by forming a space on the holder) to (13a) between.血液センサの廃棄に関して穿刺部を汚さない血液検査装置を提供すること。血液検査装置(11)は、上ホルダ(13a)と下ホルダ(13b)とからなる穿刺部(13)と、コネクタ(18)とを備え、穿刺時には、コネクタ(18)と上ホルダ(13a)と下ホルダ(13b)とがセンサ(24)を挟んで保持し、センサ排出時には下ホルダ(13b)を、上ホルダ(13a)から離れるように回動させるとともに、該回動により下ホルダ(13b)と上ホルダ(13a)間に空間を形成してセンサ(24)を露出させる。
