Abstract
A light-emitting sealed body includes a housing structure housing a gas for generating plasma. The housing structure includes a first window configured to cause first light for maintaining the plasma in a plasma region where the plasma is generated to be incident on the plasma region, a second window configured to emit second light emitted from the plasma from the plasma region, a third window facing the first window with the plasma region interposed therebetween and configured to emit the first light transmitted through the plasma from the plasma region, and a wall having a light shielding property and defining at least a light passage region of the third window.
