FOAM EJECTION DEVICE

To provide a foam ejection device capable of preventing force required for an ejection operation from becoming excessive and capable of ejecting foam having good foam quality while a volume of the foam ejected by one ejection operation is ensured as necessary.SOLUTION: A foam ejection device 500 includes a first mesh 81 and a second mesh 82, in which: the volume of the foam is V; the first mesh 81 has an area of S1, an opening ratio of E1, a circumference of each opening of L1 and a thickness of D1; the second mesh 82 has an area of S2, an opening ratio of E2, a circumference of each opening of L2 and a thickness of D2; and A1 and A2 satisfy Equation 3 and Equation 4. Where A1=V÷{S1xE1x(L1xD1)1/2}...(Formula 1), A2=V÷{S2xE2x(L2xD2)1/2}...(Formula 2), 0.3 less than or equal to A1x10-3 less than or equal to 5.0...(Formula 3), 0.3 less than...
