A second container disposed therein and a semi-solid metal slurry fixed to a lower end of the stirrer so as to protrude into the second container and discharged from the first container through the gap. A continuous sheet manufacturing facility, comprising: a guide member having a spiral guide groove formed on an outer periphery thereof; and means for sucking and exhausting the glass in the first container.
