1. A method for electronic device production using a solvent composition which is used in an ink for producing an electronic device by a printing method, comprising:
applying to a surface member by a printing method an ink comprising a miscible product of: a solvent and a compound represented by Formula (1) below:

OG Complex Work Unit Chemistry
wherein R is the same or different and represents an aliphatic hydrocarbon group having 1 or more carbon atoms,
wherein the solvent is at least one selected from propylene glycol methyl-n-propyl ether, propylene glycol methyl-n-butyl ether, dipropylene glycol methyl-n-propyl ether, dipropylene glycol methyl-n-butyl ether, dipropylene glycol methyl isoamyl ether, tripropylene glycol methyl-n-propyl ether, cyclohexyl acetate, 2-methylcyclohexyl acetate, 4-t-butylcyclohexyl acetate, and dihydroterpinyl acetate, and
wherein a weight ratio of the solvent to the compound represented by Formula (1) constituting the miscible product, the solvent:the compound, is from 100:0.01 to 100:50.
