(54) Slurry ejection apparatus, slurry application apparatus, and method for manufacturing plugged honeycomb structure


(57) A slurry ejection apparatus 1 includes: a container portion 2 containing slurry 10 therein and having a discharge port 20, a thrust-imparting portion 3 disposed in the container portion 2, and a nozzle portion 4 provided with a feed port 11 communicating with the discharge port 20 and a slit-shaped ejection port 12 for ejecting the slurry 10. The ejection port 12 is formed with a fixed length in the width direction 9 of the ejection port 12 in each position in a longitudinal direction 8 of the discharge port to almost uniformalize an ejection amount per unit time of the slurry 10 in each position in the longitudinal direction 8 of the ejection port.
