A current collector (100A, 100B) for a lead-acid battery, comprising: a frame rib; a lug provided on the frame rib; and inner ribs inside the frame rib, wherein the frame rib includes an upper element continuous with the lug, a lower element facing the upper element, and a pair of side elements (113, 114) coupling the upper element with the lower element, the inner ribs include a longitudinal rib extending in a first direction from the upper element toward the lower element, and a transverse rib extending in a second direction from one of the side elements (113, 114) toward the other of the side elements (113, 114), a striped pattern of a metallic fibrous structure is observed in a cross-section perpendicular to the first direction of the longitudinal rib, an outer peripheral region of the cross-section having a depth of at least 55 μm or more from a line corresponding to the outer surface of the longitudinal rib is made up of a first portion in which the fibrous structure extends along a contour of the cross-section and a second portion except for the first portion, wherein the first portion consists of the stripes of the fibrous structure having an angle (θ) of less than 45° with the contour of the section of the cross-section and the second portion consists of the stripes of the fibrous structure having an angle (θ) of more than 45° with the contour of the section of the cross-section and/or of the stripes of the fibrous structure whose angle (θ) with the contour of the section of the cross-section is unobservable, and a percentage of a length of the contour corresponding to the first portion to a total length of the contour of the cross-section is 50% or more. a frame rib; a lug provided on the frame rib; and inner ribs inside the frame rib, wherein the frame rib includes an upper element continuous with the lug, a lower element facing the upper element, and a pair of side elements (113, 114) coupling the upper element with the lower element, the inner ribs include a longitudinal rib extending in a first direction from the upper element toward the lower element, and a transverse rib extending in a second direction from one of the side elements (113, 114) toward the other of the side elements (113, 114), a striped pattern of a metallic fibrous structure is observed in a cross-section perpendicular to the first direction of the longitudinal rib, an outer peripheral region of the cross-section having a depth of at least 55 μm or more from a line corresponding to the outer surface of the longitudinal rib is made up of a first portion in which the fibrous structure extends along a contour of the cross-section and a second portion except for the first portion, wherein the first portion consists of the stripes of the fibrous structure having an angle (θ) of less than 45° with the contour of the section of the cross-section and the second portion consists of the stripes of the fibrous structure having an angle (θ) of more than 45° with the contour of the section of the cross-section and/or of the stripes of the fibrous structure whose angle (θ) with the contour of the section of the cross-section is unobservable, and a percentage of a length of the contour corresponding to the first portion to a total length of the contour of the cross-section is 50% or more.
