Abstract: Provided is an antifouling sheet having an antifouling layer formed of an antifouling layer-forming composition containing a specific tetrafunctional silane compound (A) and a specific trifunctional silane compound (B) wherein the content of the component (B) is 8 to 90 mol % relative to 100 mol % of the component (A), and the antifouling layer is a layer formed by drying and curing a coating film formed of the antifouling layer-forming composition, in an ammonia atmosphere. Also provided is a method for producing the antifouling sheet. The antifouling sheet is provided with an antifouling layer having good surface state and curability, has a large slip acceleration for water droppings, thereby having excellent water repellency that makes water droplets slip off instantly, and has excellent interlayer adhesiveness.
