A tapered roller bearing, comprising: an inner ring having a raceway surface having a conical shape on an outer periphery of the inner ring; an outer ring having a raceway surface having a conical shape on an inner periphery of the outer ring; a plurality of tapered rollers incorporated between both the raceway surfaces; and a cage configured to receive the tapered rollers, wherein the cage is formed of a metal material, and comprises: a small-diameter-side annular portion continuous on a small-diameter end surface side of the tapered rollers; a large-diameter-side annular portion continuous on a large-diameter end surface side of the tapered rollers; and a plurality of column portions coupling the small-diameter-side annular portion and the large-diameter-side annular portion to each other, wherein the small-diameter-side annular portion, the large-diameter-side annular portion, and the column portions define pockets configured to receive the tapered rollers, characterized in that each of the column portions facing the pockets comprises a deburring-press processed surface (1 1) on a radially inner side of a side surface of the each of the column portions, wherein the deburring-press processed surface comprises: a straight portion located at a center of the pocket in an axial direction; pocket corner rounded portions located at both ends of the pocket in the axial direction; and relief portions each formed between the straight portion and the pocket corner rounded portion, and wherein each of the relief portions has a relief amount (Δ) increased gradually from an axial end of the straight portion toward the pocket corner rounded portion, and is smoothly connected to the straight portion. an inner ring having a raceway surface having a conical shape on an outer periphery of the inner ring; an outer ring having a raceway surface having a conical shape on an inner periphery of the outer ring; a plurality of tapered rollers incorporated between both the raceway surfaces; and a cage configured to receive the tapered rollers, wherein the cage is formed of a metal material, and comprises: a small-diameter-side annular portion continuous on a small-diameter end surface side of the tapered rollers; a large-diameter-side annular portion continuous on a large-diameter end surface side of the tapered rollers; and a plurality of column portions coupling the small-diameter-side annular portion and the large-diameter-side annular portion to each other, a small-diameter-side annular portion continuous on a small-diameter end surface side of the tapered rollers; a large-diameter-side annular portion continuous on a large-diameter end surface side of the tapered rollers; and a plurality of column portions coupling the small-diameter-side annular portion and the large-diameter-side annular portion to each other, wherein the small-diameter-side annular portion, the large-diameter-side annular portion, and the column portions define pockets configured to receive the tapered rollers, characterized in that each of the column portions facing the pockets comprises a deburring-press processed surface (1 1) on a radially inner side of a side surface of the each of the column portions, wherein the deburring-press processed surface comprises: a straight portion located at a center of the pocket in an axial direction; pocket corner rounded portions located at both ends of the pocket in the axial direction; and relief portions each formed between the straight portion and the pocket corner rounded portion, and a straight portion located at a center of the pocket in an axial direction; pocket corner rounded portions located at both ends of the pocket in the axial direction; and relief portions each formed between the straight portion and the pocket corner rounded portion, and wherein each of the relief portions has a relief amount (Δ) increased gradually from an axial end of the straight portion toward the pocket corner rounded portion, and is smoothly connected to the straight portion.
