    • PROBLEM TO BE SOLVED: To provide an extraction method which selectively, very efficiently extracts a target substance from a material to be processed without a multistage extraction operation, and also provide an extraction device. SOLUTION: The target substance-extracting method includes; a process in which a high-pressure mixed fluid, in which a hydrophilic fluid component and a hydrophobic fluid component of supercritical or subcritical state are mixed over the solubility of each of the components, is contacted with a solid material to be processed which contains a target substance to extract the target substance, which is contained in the material to be processed, at least either in the hydrophilic fluid component or in the hydrophobic fluid component; a process in which a fraction whose main component is the hydrophilic fluid component and a fraction whose main component is the hydrophobic fluid component are collected from the high-pressure mixed fluid; and a process in which the target substance is separated at least one of the fractions.
