PROBLEM TO BE SOLVED: To obtain the subject polymer having improved processability, useful as an electric part material, etc., by making the polymer include both a specific phenylene unit and an oxyphenylene unit. SOLUTION: This phenol polymer is obtained by polymerizing (A) phenol with (B) a phenol derivative of the formula (R1 to R3 are each H or a 1-5C alkyl), preferably 2,4,6-trimethylphenol, etc., and contains both a hydroxyl group- containing phenylene unit and a hydroxyl group-free oxyphenylene unit. The polymer has 150-400 number-average molecular weight. The polymer is preferably obtained, to be concrete, by polymerizing the component A with the component B by using an oxidizing agent, especially a peroxide or oxygen in a mixed solvent of an organic solvent, especially a 1-4C alcohol and water in the presence of an oxidation-reduction enzyme, especially a peroxidase as a catalyst.
