PROBLEM TO BE SOLVED: To provide a handy type flux applicator with which an operator can easily grasp a specific gravity of a flux. SOLUTION: This flux applicator 1 has a flux housing part 3 in which a flux 6 is housed, a flux applying part 6 with which flux 6 housed in the flux housing part 3 is applied to a objective part for application, a measuring means 4 of the specific gravity to measure the gravity of the flux 6, and the specific gravity display part 5 to display the specific gravity of the flux 6 measured by a means 4 (specific gravity sensor) for measuring the specific gravity to the outside.
