PROBLEM TO BE SOLVED: To solve the problems wherein extraction and analysis of an agricultural chemical or the like included in food are required from requirement for safe food, and simultaneous extraction from a large quantity of food is required from the viewpoints of deterioration of an extraction component, heightening of analysis accuracy, or improvement of analysis efficiency, while supercritical extraction gradually becomes a main current. SOLUTION: This supercritical extraction apparatus 1 for extracting a sample by using a supercritical fluid is characterized as follows: the supercritical fluid is pressurized and supplied to a regulator 7 in a thermostat 11; the supercritical fluid is introduced into a plurality of extractors 8a-8f uniformly through a valve by the regulator 7; extraction is performed simultaneously as long as a fixed time by the plurality of extractors by controlling the pressure by a pressure controller 9 and by controlling the temperature by the thermostat 11; then, outlet valves of the extractors 8a-8f are switched; and a plurality of extracted liquids are taken out by capillary tubes 18a-18f and then analyzed.
