The present invention relates to a multi-injection type RF plasma processing apparatus and an RF plasm torch making manufacturing of a core-shell structure needing increase in production per unit time and heterogeneous synthesis easy, which has been a trouble during managing an existing RF thermal plasma system. The multi-injection RF plasma processing device and an RF plasma torch comprise a raw material supply part (120) a plasma torch (200) and reactor (300); two or more multi-injectors (210a,210b) spraying powder particles transferred from the raw material supply part (120) upon a high temperature plasma temperature dispersion area, and arranged on the plasma torch (200); a supporting block (400) supporting the multi-injectors (210a,210b); and an adjustment means.
