VENTILATION DEVICE

A ventilator includes, in a main body thereof, an electrical equipment box (70) including an electrical equipment case (71) in which an electronic substrate (73) that drives blowers is disposed, and an electrical equipment cover (72) that covers the electrical equipment case (71) and the electronic substrate (73), the ventilator including a terminal block mounting plate (81) to which a terminal block (83) is mounted, the terminal block (83) including an external power supply line connection terminal that connects an external power supply line at one end portion and an internal electric wire connection terminal that connects an internal electric wire connected to the electronic substrate (73) at the other end portion; in which the terminal block mounting plate (81) includes a terminal block mounting surface (81a) that holds the terminal block (83) in a state where a direction in which a side surface on a side of the one end portion of the terminal block (83) faces has an angle with respect to an outer surface (70a) of the electrical equipment box (70) in a direction external to the electrical equipment box (70), and a direction in which a side surface on a side of the other end portion of the terminal block (83) faces has an angle with respect to the outer surface (70a) in a direction internal to the electrical equipment box (70).
