PROBLEM TO BE SOLVED: To prevent an injection valve device of a high-pressure homogenizer from being clogged with solidified raw material and allowing easy control of inner pressure by keeping the injection interval of the injection valve constant, in the injection valve of the high pressure homogenizer used for dispersing and emulsifying a raw material such as a suspension containing fine solid matter as the raw material dispersed in a liquid, and used for efficiently pulverizing or processing a raw material such as crushing cell membranes of fungus in a liquid, and to provide an injection valve unit. SOLUTION: The injection valve device of a high-pressure homogenizer has a small diameter orifice 3 formed in a high-pressure homogenizing mechanism section 1 through which a raw material G consisting of a suspension 2 containing fine solid matter suspended in a liquid is made to pass at a high pressure, and comprises a fixed member 5 having a raw material introduction path 4 and a movable member 6 disposed freely turnably, swingably and pulsatingly in the axial direction I. The orifice of the injection valve is made of a fine gap K in the radial direction R between the fixed side end face 5a of the fixed member and the movable side end face 6a of the movable member 6, and communicates with a material processing path 8 via an annular collision wall 7.
