An electric discharge lamp device prevents a temperature rise in the circuit device when an electric discharge lamp (30) is operated without the use of a high voltage wire and a high voltage connector. The electric discharge lamp device includes a reflecting member (20) and a circuit device (40) that is directly connected with the electric discharge lamp (30) without using a high voltage wire. The distance between the reflecting member (20) and the circuit device (40) is set at a value not less than 6 mm. In operation, a beam of light emitted from the electric discharge lamp (30) is reflected forward by a concave reflecting face of the reflecting member (20).
