This phenolic resin to be blended with rubber is characterized in that, regarding a chemical shift measured with 13C-NMR, when the total peak surface area in 110-160 ppm is defined as 100, the total peak surface area in 0 ppm or more but less than 60 ppm is 80-400, while the total peak surface area of 60 ppm or more but less than 110 ppm is 2-70. Cette résine phénolique à mélanger avec du caoutchouc est caractérisée en ce que, concernant un décalage chimique mesuré avec la RMN 13C, lorsque la surface de crête totale comprise entre 110 et 160 ppm est définie comme étant égale à 100, la surface de crête totale de 0 ppm ou plus mais inférieure à 60 ppm est de 80 à 400, tandis que la surface de crête totale de 60 ppm ou plus mais inférieure à 110 ppm est de 2-70. 本発明に係るゴム配合用フェノール樹脂は、１３Ｃ－ＮＭＲによる化学シフト、１１０ｐｐｍ以上１６０ｐｐｍ以下のピーク面積の総和を１００としたとき、０ｐｐｍ以上６０ｐｐｍ未満のピーク面積の総和が８０～４００であり、６０ｐｐｍ以上１１０ｐｐｍ未満のピーク面積の総和が２～７０であることを特徴とする。
