Blood component measurement device and blood component measurement method

A blood component measurement device that measures a blood component amount using a biosensor in which blood is introduced and then a blood component contained in said blood is subjected to oxidation-reduction using an oxidoreductase,

• wherein the blood component measurement device includes:
• a first current value measure that detects, as a first current value, an oxidation-reduction current that is generated by the oxidation-reduction when a first voltage is applied to a first electrode pair composing the biosensor;
• a second current value measure that detects, as a second current value, a current that is generated when a second voltage is applied to a second electrode pair composing the biosensor;
• a controller that exerts control so that, over a predetermined period after the introduction of the blood into the biosensor, the first current value measure measures the first current value multiple times, with the first voltage being continuously applied to the first electrode pair, and the second current value measure measures the second current value, with the second voltage being applied;
• a converter that converts, to blood component amounts, pairs of any one of a plurality of first current values measured by the first current value measure and the second current value measured by the second current value measure;
• and
• a calculator that calculates the blood component amount for the blood introduced into the biosensor, using a plurality of the blood component amounts converted by the converter.
