1. A condensate trap apparatus comprising:
an inlet, through which condensate is introduced;
a storage space, in which the condensate introduced from the inlet is stored;
a discharge part including an outlet configured to discharge the stored condensate from the storage space; and
a buoyant body including a closed part formed to be convex toward a vertically lower side such that the buoyant body is seated on the discharge part to close the outlet, a columnar support part extending vertically upwards from the closed part, and a weight formed of a material having a density that is higher than that of a material constituting the support part, at a lower end of the closed part.
