Claim 10:
11. The insulation resistance detection apparatus according to claim 6, wherein:
the at least one predetermined determination voltage includes at least a first type determination voltage and a second type determination voltage;
the insulation resistance detection apparatus further comprises
a storage unit that stores the first type determination voltage and the second type determination voltage; and

the resistance determiner is configured to:
select, in a current activated state of the power system, one of the first type determination voltage and the second type determination voltage based on at least one value of the insulation resistance determined thereby in an immediately previous activated state of the power system; and
determine a value of the insulation resistance between the ground portion and the power-supply path based on the selected one of the first type determination voltage and the second type determination voltage.
