Abstract
The present invention uses a flux containing a rosin, a solvent, a thixo agent, and an activator. The thixo agent contains a polyamide and a compound represented by general formula (1). The polyamide is a condensate between an amine and at least one selected from aliphatic carboxylic acids and hydroxy group-containing aliphatic carboxylic acids, and has an endothermic peak at a temperature of 120-200° C. In the general formula, Rrepresents a hydrocarbon group having 11-30 carbon atoms. Rrepresents a hydrogen atom or a hydrocarbon group having 12-31 carbon atoms. Rrepresents an n-valent hydrocarbon group having 4-12 carbon atoms. Rrepresents an alkylene group having 2-6 carbon atoms. Rrepresents a single bond or an alkylene group having 2-6 carbon atoms. n represents 1 or 2. When n represents 1, m represents an integer of 1-3. When n represents 2, m represents 1.
