An ECU executes a program including the steps of: determining whether an insulation resistance Ri is smaller than a threshold value Ri(0); if the insulation resistance Ri is smaller than the threshold value Ri(0), determining whether there is electric leakage between a vehicular body and an EHC and whether there is a possibility that there is electric leakage at a location other than a location between the vehicular body and the EHC; and if there is electric leakage between the vehicular body and the EHC, performing heating control.
