1. A nozzle, comprising:
a pattern shim having a plurality of tapered first convex portions protruding from an outer edge outwardly;
an adhesive shim having a plurality of tapered second convex portions protruding from an outer edge outwardly and having a shape wider than the plurality of tapered first convex portions;
a gas shim having a plurality of tapered third convex portions protruding from an outer edge outwardly and having a shape wider than the plurality of tapered first convex portions;
a head body having an adhesive inlet, an adhesive outlet, and an adhesive flow path connecting the adhesive inlet and the adhesive outlet;
