Abstract
This flux contains a first solvent and a thixotropic agent. The first solvent either has a viscosity of 10 Pa·s or more at 30° C. or is a solid at 30° C., has a boiling point of 200° C. or more, and has a weight loss rate of less than 96 mass % when heated to 230° C. The thixotropic agent contains a polyamide that is one or more substances selected from the group consisting of condensates of an aliphatic carboxylic acid and an amine and condensates of an aliphatic carboxylic acid, a hydroxy group-containing aliphatic carboxylic acid, and an amine. The content of the first solvent is 30 mass % or more with respect to the total mass of flux. The content of the polyamide exceeds 2 mass % with respect to the total mass of flux.
