An emulsifying apparatus for solid-liquid multiphase flow and a nozzle for solid-liquid multiphase flow, whereby, in a high pressure vessel, there is provided a plate member made of a material with high hardness and having a through-hole sufficiently small compared with a passage of fluids in the high pressure vessel. An outflow passage perpendicular to the through-hole is communicated to a side of the plate member at the center of the through-hole of the plate member, the through-hole of the plate member forms an orifice, cross-sectional area of said orifice, obtained by cutting central axis of the passage by a vertical plane, being gradually reduced from inlet of the nozzle toward the center, and there is provided an area without particles from a portion with minimum orifice diameter toward the center, and an orifice is provided, cross-sectional area of said orifice, obtained by cutting central axis of flow passage by a vertical plane, being gradually reduced from inlet toward the outlet of the nozzle, and there is provided an area without particles from a portion with minimum orifice diameter toward the outlet.
