In the present battery apparatus for vehicle, a temperature detecting plate (30) is fixed outside a casing (10) accommodating a plurality of secondary batteries (20). The casing (10) is provided with ventilation holes (15) for cooling the secondary batteries (20) between the secondary batteries (20) and the temperature detecting plate (30). The temperature detecting plate (30) fixes temperature sensors (50) on an insulation substrate (31). The insulation substrate (31) has air holes (33) communicated with the ventilation holes (15) of the casing (10), and a communicating portion (34) is provided between the air holes (33), and the temperature sensor (50) is fixed to the communicating portion (34), whereby the temperature sensor (50) is located so as to access to the surface of the secondary battery (20) via the ventilation hole (15).
