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 (A) 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 (A) of the recesses , which is a cross-sectional area of a space defined by a closed curve (L) 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 (L) that contacts with each radial outer end of the protrusions as an outer circumferential surface, and the closed curve (L) is a circular shape or an elliptical shape of which center is a central axis (O) 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 (A) 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 (A) of the recesses , which is a cross-sectional area of a space defined by a closed curve (L) 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 (L) that contacts with each radial outer end of the protrusions as an outer circumferential surface, and the closed curve (L) is a circular shape or an elliptical shape of which center is a central axis (O) of the optical fiber cable . in a transverse cross-sectional view, a cross-sectional area (A) 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 (A) of the recesses , which is a cross-sectional area of a space defined by a closed curve (L) 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 (L) that contacts with each radial outer end of the protrusions as an outer circumferential surface, and the closed curve (L) is a circular shape or an elliptical shape of which center is a central axis (O) of the optical fiber cable . <EOS>
