An abnormality judgment apparatus provided with a processing part, a communicating part able to communicate with a mobile object provided with a power reception apparatus receiving power wirelessly transmitted from a power transmission apparatus installed on a road, and a storage part storing power reception history information received from the mobile object. The processing part calculates a probability of occurrence of an abnormality in the power reception apparatus of the mobile object based on the power reception history information and detects a presence of an abnormality occurring location where the power transfer efficiency becomes less than a predetermined value and judges that an abnormality has occurred in the power transmission apparatus installed at the abnormality occurring location when an abnormality occurring location is detected and the probability becomes less than a predetermined judgment threshold value.
