A purpose of the present invention is to provide a flux having an improved cleaning property by suppressing a carbonization of a flux residue. A flux contains an organic acid, a thixotropic agent, rosin and a solvent wherein a fatty acid monoalkylol amide having 14-20 carbon atoms is contained as the thixotropic agent. The fatty acid monoethanol amide is added in an amount of 3-10% by weight as the thixotropic agent. In addition, a dicarboxylic acid having 10 or less carbon atoms is added in an amount of 4-10% by weight as the organic acid. Moreover, the solvent is added in an amount of 30-60% by weight.
