PROBLEM TO BE SOLVED: To replenish a container with a solution without scattering the solution and to sufficiently achieve the safety of a worker or the prevention of the pollution of the periphery, in a sample pretreatment apparatus for fluorescent X-ray analysis for dropping a solution on a substrate after dissolving the object to be measured present on the surface or the like of the substrate by reactive gas and moving the dropped solution on the surface of the substrate while holding the same by a holder and recovering the object to be measured. SOLUTION: The sample pretreatment apparatus for fluorescent X-ray analysis is equipped with a container 83 housing the solution 4 and loaded with pressure from a pressure source, a pressure supply valve 85 for opening and closing the piping to the container 83 from the pressure source, the escape valve 88 provided to the piping between the pressure supply valve 85 and the container 83 or the like.
