Abstract

The present invention includes a body case having a biological sample sensor mounting portion on one end side, a temperature sensor (A) provided on the one end side inside the body case, a measurement portion connected to the biological sample sensor mounting portion, and a control portion connected to the measurement portion. A temperature sensor (B) is provided on one other end side inside the body case, and when measurement is performed by the measurement portion, temperature change amounts in the two end portions are compared using the temperature sensors (A) and (B). Furthermore, a measurement value obtained by the measurement portion is corrected using temperature information from either one of the temperature sensors (A) or (B) that is provided in the end portion on the side where the temperature change is smaller.

Claims
