Abstract: Erroneous mounting of a semiconductor power module can be more easily detected. A semiconductor power module (9) according to the present invention includes: a status signal generation unit (90) configured to detect a status in the semiconductor power module (9) and generate and output a status signal indicating the detected status; an identification information storage unit (91) configured to preliminarily store identification information for identifying the semiconductor power module (9) and output an identification signal indicating the identification information; and a switching unit (92) configured to select one of the status signal output from the status signal generation unit (90) and the identification signal output from the identification information storage unit (91) and output the selected signal to an outside of the semiconductor power module (9).
