An object of the present invention is to provide a chemical liquid which makes it difficult for a defect to occur on a substrate after development. Another object of the present invention is to provide a chemical liquid storage body and a pattern forming method.
The chemical liquid of the according to an embodiment of the present invention contains a main agent which is formed of one kind of organic solvent or formed of a mixture of two or more kinds of organic solvents, an impurity metal, and a surfactant, in which a vapor pressure of the main agent is 60 to 1,340 Pa at 25° C., the impurity metal contains particles containing one kind of metal selected from the group consisting of Fe, Cr, Ni, and Pb, in a case where the chemical liquid contains one kind of particles, a content of the particles in the chemical liquid is 0.001 to 30 mass ppt with respect to a total mass of the chemical liquid, and in a case where the chemical liquid contains two or more kinds of particles, a content of each kind of the particles in the chemical liquid is 0.001 to 30 mass ppt with respect to the total mass of the chemical liquid.
