Abstract
A flux for a resin flux cored solder or a flux coated solder, in which scattering of flux and solder in using the solder is suppressed, and a resin flux cored solder or a flux coated solder including such a flux are provided. The flux for a resin flux cored solder can include a rosin resin, an activator, and at least one selected from an acrylic polymer and a vinyl ether polymer, which has a weight average molecular weight of 8000 to 100000, in an amount of 0.1 to 3 mass-% based on the total mass of the flux.
