To provide an antifouling layer-provided transparent substrate, which is excellent in antiglare and antifouling properties, especially in removability of a creamy product such as hand cream. An antifouling layer-provided transparent substrate, containing a transparent substrate and an antifouling layer provided as the top surface layer on one main surface of the transparent substrate, where the antifouling layer has a divalent group represented by —(OCF)(OCFCF)— (where v and w are each independently an integer of at least 1), and the surface of the antifouling layer is such that the mean width RSm of the elements and the arithmetical mean roughness Ra satisfy RSm≥Ra×100+5. 1. An antifouling layer-provided transparent substrate , comprisinga transparent substrate andan antifouling layer provided as the top surface layer on one main surface of the transparent substrate, wherein{'sub': ['2', 'v', '2', '2', 'w'], '#text': 'the antifouling layer has a divalent group represented by —(OCF)(OCFCF)—, where v and w are each independently an integer of at least 1, and'}{'claim-text': {'br': None, 'i': 'RSm≥Ra×', '#text': '100+5\u2003\u2003(I).'}, '#text': 'the surface of the antifouling layer is such that the mean width RSm of the elements and the arithmetical mean roughness Ra satisfy the following formula (I):'}2. The antifouling layer-provided transparent substrate according to claim 1 , wherein the surface of the antifouling layer has a skewness Rsk of from −1.3 to 1.3.3. The antifouling layer-provided transparent substrate according to claim 1 , wherein the fluorine content surplus of the antifouling layer calculated by the following method is from 10 to 150:{'claim-text': {'br': None, 'i': ['F', 'F', 'F'], '#text': 'Fluorine content surplus=(1−2)/2×100\u2003\u2003(II).'}, '#text': 'the fluorine content surplus is calculated by the following formula (II) from the fluorine atom intensity F1 in the antifouling layer of the antifouling layer-provided transparent substrate, ...
