Provided is a polycarbonate polyol used as a raw material of a polyurethane that yields a polyurethane solution having good storage stability and exhibits excellent flexibility and solvent resistance. This polycarbonate polyol is a polycarbonate diol that includes structural units represented by the following Formulae (A) and (B), wherein, R.sup.1 and R.sup.2 each independently represent an alkyl group having 1 to 4 carbon atoms and, in this range of the number of carbon atoms, optionally have an oxygen atom, a sulfur atom, a nitrogen atom, a halogen atom, or a substituent containing these atoms; and R.sup.3 represents a linear aliphatic hydrocarbon having 3 or 4 carbon atoms. This polycarbonate diol has a molecular weight of 500 to 5,000, and the value of the following Formula (I) is 0.3 to 20.0: (Content ratio of branched-chain moiety in polymer)/(Content ratio of carbonate group in polymer)×100(%) (I). ##STR00001##
