1. An effective component generation device comprising:
an internal device including a discharger that generates an effective component;
a case having a box shape having a discharge port through which the effective component is discharged, the case housing the internal device; and
a lid body joined to the case, wherein:
the case includes a metal body including a bottom plate and peripheral walls, the bottom plate and the peripheral walls surrounding at least the discharger in the internal device,
the metal body includes a seamless portion at a corner portion between two surfaces of adjacent peripheral walls oriented in different directions,
the case has an opening provided at a position different from a position of the discharge port, and the lid body is joined to the case, closing the opening in a state where the internal device is housed between the lid body and the case,
the case and the lid body are joined to each other at a plurality of joints disposed at positions around the opening, the plurality of joints including at least a first joint, a second joint, a third joint, and a fourth joint, and
the first joint, the second joint, the third joint, and the fourth joint are disposed in such a manner that a first straight line connecting the first joint and the second joint and a second straight line connecting the third joint and the fourth joint intersect each other in the opening.
