There are provided an optical fiber ribbon and optical fiber cable which suppress the deterioration of polarization mode dispersion and contribute to the increase of communication capacity in wavelength division multiplexing. An optical fiber ribbon includes a plurality of optical fiberstied in a bundle and a ribbon coating layerformed around the plurality of optical fibers to integrate the plurality of optical fibers, wherein the glass-transition temperature of the coating ranges from 80&#xb0; C. to 130&#xb0; C. and 'a' is 0.01 mmor less, where 'a' is a sectional area of the ribbon coating layerin a cross section in which outer half of the optical fiber at an edge of the ribbon and the coating of the optical fiber ribbon are taken along a line passing the center of the glass optical fiber positioned at one of edges of the ribbon out of the plurality of the optical fibers and being perpendicular to the horizontal plane of the optical fiber ribbon.
