A patterned substrate includes a base layer; a droplet holding space
surrounded by a barrier that is formed over the base layer; and a pattern
formed by discharging droplets containing a pattern formation material
into the droplet holding space surrounded by the barrier. A recess that
is lyophilic with respect to the droplets and that expands outward in a
planar direction of the base layer is provided on a base layer side of
the barrier.
