PROBLEM TO BE SOLVED: To provide a water immersion amount estimation apparatus in which the erroneous selection of information on a water immersion amount does not occur when the water immersion amount of one power apparatus among a plurality of power apparatuses is estimated.SOLUTION: An estimation device for estimating a water immersion amount of one power apparatus is mounted on a surface attached with identification information of the power apparatus on the basis of a storage device in which a plurality of water immersion amount information showing a relationship between respective temperature rises of a plurality of power apparatuses when the plurality of power apparatuses is heated respectively by a predetermined time, a reading device for reading the identification information attached to the plurality of power apparatuses, a temperature rise of the one power apparatus when the one power apparatus whose identification information is read by the reading device is heated by the predetermined time, and a water immersion amount corresponding to the one power apparatus whose identification information is read by the reading device among the plurality of pieces of the water immersion information stored by the storage device. |
