In the present battery apparatus for a vehicle, a temperature detecting plateis fixed outside a casingaccommodating a plurality of secondary batteries. The casingis provided with ventilation holesfor cooling the secondary batteriesbetween the secondary batteriesand the temperature detecting plate. The temperature detecting platefixes temperature sensorson an insulation substrate. The insulation substratehas air holescommunicated with the ventilation holesof the casing, and a communicating portionis provided between the air holes. The temperature sensoris fixed to the communicating portion, and thereby the temperature sensoris located so as to have access to a surface of the secondary batteryvia the ventilation hole
