PROBLEM TO BE SOLVED: To fix, recover or observe a specific minute object such as a DNA molecule, a cell or a microorganism from a mixture with the other minute objects. SOLUTION: The method for fixing a minute object of the present invention comprises steps of: fixing the minute object together with a gelled medium on a support material by locally gelling the medium in the circumference of the minute object to be fixed in a system comprising the medium capable of reversibly carrying out sol-gel phase transition, the support material and the minute object; adding a photocurable resin to this system; and irradiating the circumference of the gelled medium with light effective for curing the photocurable resin. Furthermore, after fixing the minute object by the method, the gelled medium containing the minute object is collected from the cured photocurable resin or the minute object is collected from the photocurable resin by making the medium in the cured photocurable resin into sol.
