PROBLEM TO BE SOLVED: To provide a static mixer which does not have defects as for axial inhomogeneities in the case single mixed element is used or when it is used together with built-in devices of a minimum number of structure elements, and can secure a mixture of high quality at a low built-in device cost. SOLUTION: The static mixer 1 for a low viscosity fluid 20 contains built-in devices 10 effective for mixing, which are arranged in a pipe 3 conducting the fluid or in a container. The built-in devices include structure elements 11, 11' and 12 in the form of flat, folded or curved sheet metal-like flow obstacles to achieve a flow of the first order. The structure elements can be explained as segments, webs, plates and/or vanes. The structure elements are geometrically modified at surfaces and/or at edges so that local flows of the second order can be induced by the modifications which are superimposed on the flow of the first order and so improve the mixing quality.
