A sensor insertion device comprises a lower case and an upper case. A base holder and a needle holder are disposed in the lower case. A needle holder raising mechanism is disposed above the needle holder. A sensor base having a sensor unit is held by the base holder. When the upper case is pushed down, the base holder and the needle holder move toward an opening on the lower surface side of the lower case, and the needle holder is raised by the needle holder raising mechanism. A protrusion that holds the upper case on the lower case is provided to the upper case in a state in which the upper case has been pushed down until the opening on the lower surface side comes into contact with the skin.

A biosensor chip is placed in a biosensor device and is rotated while a biochemical analysis specimen is measured, the biosensor chip comprising a main body, a holding chamber, a dispensing chamber, a plurality of quantification chambers, and a plurality of measurement chambers. The main body has an inlet into which the specimen is poured. The holding chamber holds the poured specimen inside the main body. The dispensing chamber is connected to the holding chamber via a first channel and dispenses the specimen. The quantification chambers are connected to the dispensing chamber, hold a specific amount of the dispensed specimen, and are disposed at positions located away from a rotational center of a rotary motion according to a distance from the first channel. The measurement chambers are connected to the quantification chambers via a second channel and react the specimen with a biochemical analysis reagent.
