An optical fiber cable comprising: a sheath; and a core which is housed in the sheath and which has an intermittently-adhered optical fiber ribbon including a plurality of optical fibers and a plurality of adhesive portions for intermittently adhering the plurality of optical fibers in a longitudinal direction, wherein recesses and protrusions are formed so as to be disposed alternately in a circumferential direction on an outer circumferential surface of the sheath, and the recesses each include two connecting portions respectively connected to radial inner ends of two adjacent protrusions, and a bottom surface positioned between the two connecting portions, the optical fiber cable characterized in that: in a transverse cross-sectional view, a cross-sectional area of the recesses is within a range of 1.3 mm 2 or more and 4.8 mm 2 or less, where the cross-sectional area of the recesses, which is a cross-sectional area of a space defined by a closed curve tangent to radial outer ends of the plurality of protrusions and all the recesses, is a difference in a cross-sectional area of the optical fiber cable with respect to a cross-sectional area of a virtual optical fiber cable having the closed curve that contacts with each radial outer end of the protrusions as an outer circumferential surface, and the closed curve is a circular shape or an elliptical shape of which center is a central axis of the optical fiber cable. a sheath; and a core which is housed in the sheath and which has an intermittently-adhered optical fiber ribbon including a plurality of optical fibers and a plurality of adhesive portions for intermittently adhering the plurality of optical fibers in a longitudinal direction, wherein recesses and protrusions are formed so as to be disposed alternately in a circumferential direction on an outer circumferential surface of the sheath, and the recesses each include two connecting portions respectively connected to radial inner ends of two adjacent protrusions, and a bottom surface positioned between the two connecting portions, the optical fiber cable characterized in that: in a transverse cross-sectional view, a cross-sectional area of the recesses is within a range of 1.3 mm 2 or more and 4.8 mm 2 or less, where the cross-sectional area of the recesses, which is a cross-sectional area of a space defined by a closed curve tangent to radial outer ends of the plurality of protrusions and all the recesses, is a difference in a cross-sectional area of the optical fiber cable with respect to a cross-sectional area of a virtual optical fiber cable having the closed curve that contacts with each radial outer end of the protrusions as an outer circumferential surface, and the closed curve is a circular shape or an elliptical shape of which center is a central axis of the optical fiber cable. in a transverse cross-sectional view, a cross-sectional area of the recesses is within a range of 1.3 mm 2 or more and 4.8 mm 2 or less, where the cross-sectional area of the recesses, which is a cross-sectional area of a space defined by a closed curve tangent to radial outer ends of the plurality of protrusions and all the recesses, is a difference in a cross-sectional area of the optical fiber cable with respect to a cross-sectional area of a virtual optical fiber cable having the closed curve that contacts with each radial outer end of the protrusions as an outer circumferential surface, and the closed curve is a circular shape or an elliptical shape of which center is a central axis of the optical fiber cable.
