PROBLEM TO BE SOLVED: To enable a user to simply carry out calibration without forcing the user to carry out complex work relating to calibration.SOLUTION: The diagnostic package 1 includes a tray 70, a probe 10, an adjusting jig 30, and a package bag 90. The adjusting jig 30 includes: a jig body 31 an insertion hole 34 formed in the jig body 31 and opened at an end face 32 of the jig body 31 a strip 50 crossing the insertion hole 34 and penetrating to the outside of the jig body 31 in the insertion hole 34, and being extractable from the jig body 31 a first calibration target 51 set on the strip 50 and a second calibration target 52 arranged at the end of the insertion hole 34. In a state where a projection light reception part 12 of the probe 10 is inserted into the insertion hole from the opening of the insertion hole 34 and the first calibration target 51 confronts the projection light reception part 12, the probe 10 and the adjusting jig 30 are housed in the tray 70.
