A method for manufacturing a packing made of a three-dimensional net-like structure which constitutes an internal structure of device which performs material transfer, heat exchange or mixing between gases, liquids or gas and liquid, the internal structure being divided in a plurality of chambers or channels connected to one another is provided. Knots where three line elements (23) converge and disperse are sequentially formed in the order of a first knot K1 formed in a hypothetical channel C1, a second knot K2 formed in a space where a rotor R3 is disposed, a third knot K3 which is formed in a hypothetical channel C2, and a fourth channel K4 formed in the space where the rotor R3 is disposed. By repeating this cycle by a desired number of times, a three-dimensional net-like structure (21) of a desired size can be manufactured.
