摘要：
Provided is a production method for a dried Vitrigel membrane whereby a dried Vitrigel membrane having a smooth surface without wrinkles is able to be obtained in a simple manner. The production method for a dried Vitrigel membrane includes, in the following order: step 1 of concentrically arranging and disposing member A having one or more recesses and member B having one or more through holes, such that the recesses overlap the through holes； step 2 of pouring a sol from the through holes of member B； step 3 of gelling the sol； step 4 of drying and vitrifying the hydrogel obtained in step 3 in a state in which it is formed in the member A and the member B； step 5 of hydrating the dried hydrogel obtained in step 4； step 6 of drying and re-vitrifying the Vitrigel obtained in step 5； and step 7 of cutting off a portion, which slightly covers the top surface of the member A, of the dried Vitrigel obtained in step 6.
