PROBLEM TO BE SOLVED: To provide an inexpensive new lignin phenolic resin with a low content of unreacted substances. The present invention also provides a process for producing such a novel lignin phenolic resin, and a method for producing a lignin phenolic resin with a high yield with little residual unreacted phenol and unreacted lignin. And a lignin phenol resin characterized by reacting 0.1-5 mol of terpene with the phenol. Moreover, it is a manufacturing method of the lignin phenol-type resin characterized by making 0.1-5 mol terpene react with a lignin raw material, phenol, and the said phenols. |
