PROBLEM TO BE SOLVED: To provide a carbodiimide compound with which a problem of conventional technology can be solved, and with which a crosslinked resin and the like, and a thermosetting resin remarkably improved in strength and adhesion and the like, are obtained when using as a crosslinking agent of resin and the like, or a thermosetting resin. SOLUTION: A polycarbodiimide compound given by following general formula (1) and having a number average molecular weight of 300-100,000, are provided. (In the formula, m=1-20, n=2-30, R is a residual group of diisocyanate, X is a urethane bond and/or urea bond, Y is a residual group of diol and/or diamine, and A and B are terminal groups).
