A high-carbon steel wire rod contains specific chemical components, with the remainder made up by Fe and impurities. In the high-carbon steel wire rod, the area ratio of pearlite is 95% or more, with the remainder being a non-pearlite structure comprising at least one material selected from bainite, pseudo-pearlite, proeutectoid ferrite and proeutectoid cementite, in a cross section perpendicular to the length direction; the pearlite has an average block particle diameter of 15 to 35 μm, wherein the area ratio of a portion of the pearlite which has a block particle diameter of 50 μm or more is 20% or less; and a region having a lamellar spacing of 150 nm or less makes up 20% or less of the pearlite in a zone extending from the surface to a depth of 1 mm. |
