A process produces an N,N',N''-trisubstituted isocyanuric acid represented by following Formula (4): wherein R is a hydroxyl-protecting group, by heating an N-substituted carbamic acid derivative represented by following Formula (1): wherein R has the same meaning as defined above; and Z is a group represented by following Formula (2) or (3): wherein R' is a hydrocarbon group or a heterocyclic group having a carbon atom at the bonding site with the adjacent oxygen atom, wherein the heating is carried out at a temperature in a range of 95° C. to 145° C. where Z is the group represented by Formula (3). This process can easily and conveniently produce the N,N',N''-trisubstituted isocyanuric acid in a high yield.
