A needle valve (24c) of a valve shaft (24) approaches a valve seat (65) while advancing into an orifice section (66). In a cross section through which an axis line (O) of an inflow pipe (IT) through which fluid flows into a valve chamber (21) and an axis line (L) of the valve shaft (24) pass, the axis line (O) of the inflow pipe (IT) and the axis line (L) of the valve shaft (24) intersect each other in the valve chamber (21). An end face (64) of a valve seat member (60) is positioned near the axis line of the inflow pipe (IT) in the cross section, and the valve chamber (21) is provided with a space (SP) into which fluid flows, on the opposite side from the inflow pipe (IT) with the end face (64) therebetween, inside a region (RG) wherein the inner circumference of the inflow pipe (IT) is extended along the axis line (O).
