PROBLEM TO BE SOLVED: To provide a lamp house for facilitating lamp replacing work. SOLUTION: A lamp 500 in a cylindrical shape has a lamp anode 500A and a lamp cathode 500K mounted at both ends of a cylindrical portion. A light is taken out of one end. A lamp house anode 301 and a lamp house cathode 401 supported by ceramics 200, 210, 220 have contact with the lamp anode 500A and the lamp cathode 500K, respectively, to supply power to the lamp. An anode holder 300 having the elastic lamp house anodes 301 arrayed in a circumferential direction is mounted inside the cylindrical ceramics 200, 201, 220. A cathode holder 400 contacts the lamp cathode 500K and abuts the ceramics 200 at its opening end. |
