A bodily fluid testing device for puncturing the skin to collect a small amount of bodily fluid and to measure a component of the bodily fluid, wherein the bodily fluid testing device is detachably attached to the case and the fingertip puncturing device. A puncture member having a puncture needle that can be protruded for, a detection chip that is detachably attached to the body fluid testing device and contains a reagent that reacts with a specific component in the body fluid, and a body fluid guide path to the detection chip. A detection tip member, a puncture member mounting portion, a puncture start switch, and an elastic member for biasing the puncture member mounting portion, and a puncture needle formed substantially airtight except for a puncture needle protrusion. A suction device including a puncture needle drive mechanism for performing temporary projection and an electric pump, and for sucking a peripheral portion including a puncture site of a fingertip by the puncture needle by sucking the inside of the puncture needle drive mechanism. A suction mechanism operation function for detecting operation of a puncture needle drive mechanism including the puncture start switch and starting operation of the suction mechanism based on the detection result, and a suction mechanism control mechanism for stopping operation of the suction mechanism; A decompression state releasing mechanism for releasing the decompression state in the puncture needle driving mechanism by the suction mechanism, a detection mechanism for detecting the state of the detection chip after contact with the bodily fluid, and a bodily fluid state based on a detection result by the detection mechanism. A body fluid inspection device comprising: a body fluid state evaluation mechanism to be evaluated; and a display mechanism for displaying an evaluation result by the body fluid state evaluation mechanism. The puncture member and the detection tip member constitute an integrated tip puncture needle assembly, and the tip puncture needle assembly has an annular opening that can be in close contact with a fingertip above the cutting edge of the puncture needle, The body fluid testing device according to claim 1, wherein one end opening of the guide path projects into the annular opening, and the other end extends to the tip. The body fluid testing device according to claim 1, wherein the suction mechanism control mechanism stops the operation of the suction mechanism using a state change signal of the detection chip detected by the detection mechanism. The body fluid testing device according to any one of claims 1 to 3, wherein the depressurized state releasing mechanism is a minute suction port that communicates a depressurized formation space depressurized by the suction mechanism with the outside of the depressurized formation space. The body fluid testing device according to claim 1, wherein the depressurized state releasing mechanism is a valve that can communicate a depressurized formation space depressurized by the suction mechanism and the outside of the depressurized formation space. The body fluid testing device according to any one of claims 1 to 5, wherein the body fluid testing device includes a pressure detection unit configured to detect a pressure in the puncture needle driving mechanism that is reduced in pressure by the suction mechanism. The body fluid testing device includes a control unit including the suction mechanism control mechanism and the body fluid state evaluation mechanism, and a pressure sensor for electrically detecting a pressure inside the puncture needle driving mechanism, which is electrically connected to the control unit. 7. The body fluid testing device according to claim 1, further comprising a puncture start detection sensor for detecting the start of puncture by the puncture needle, and a display unit. 8. The body fluid testing device according to claim 1, further comprising a storage unit configured to store an evaluation result obtained by the body fluid state evaluation mechanism, and an external output unit configured to output the evaluation result data stored in the storage unit to an external device. The body fluid testing device according to any one of the above. The body fluid testing device according to any one of claims 1 to 8, wherein the body fluid testing device includes a voice output unit that notifies information from the body fluid state evaluation mechanism by voice.
