<p>A component measuring device (1) has a blood measuring mode in which the blood sugar level is determined by measuring a test paper (53) to which a blood adheres and a test liquid measuring mode in which the blood sugar level by measuring a test paper (53) to which a test liquid adheres. Adequate first analytical curves corresponding to lots and adequate second analytical curves corresponding to lots are stored in a data storage section (13). Calibration numbers each for specifying an analytical curve are allocated to the first and second analytical curves. A calibration number for specifying adequate first and second analytical curves corresponding to the lot is indicated on each container of a chip (5).</p>
