Abstract
A sensor substrate includes a base and fibrous projections on an upper surface of the base. The fibrous projections have fixed ends fixed to the upper surface of the base and free ends opposite to the fixed ends, respectively. The fibrous projections provide a fixed end-side region including the fixed ends and a free end-side region including the free ends. The total surface area at which the fibrous projections in the fixed end-side region is larger than that in the free end-side region.
