A foam discharge device (100) is configured in such a manner that a piston (41) for liquid is fitted in a cylinder section (30a) for liquid, a piston (73) for air is fitted in a cylinder section (30b) for air, foam is produced by the mixing of liquid within the cylinder section (30a) for liquid and air within the cylinder section (30b) for air by means of the vertical movement of an operation member (A), and the foam is discharged from a nozzle (83). An outside air introduction hole (76) is open in a partition wall (72), and a water entry prevention sidewall section (77) for preventing water from entering the outside air introduction hole (76) rises from at least a portion of the edge of the outside air introduction hole (76).
