Abstract: A discharge lamp includes a housing including a dielectric portion having a light transmission area formed of a dielectric material and transmitting light, and a main body portion forming a discharge-gas-filled space together with the dielectric portion, the discharge-gas-filled space being filled with a discharge gas; an electron emission source disposed in the discharge-gas-filled space to face the light transmission area; a discharge path limiting member separating the electron emission source and the light transmission area, in the discharge-gas-filled space, and including an electron passage hole that transmits electrons emitted from the electron emission source; and an external electrode disposed at an outer side of the housing to face the electron emission source across the dielectric portion, and including an opening that passes the light transmitted through the light transmission area.
