PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device in which electric connection between a ground electrode of a substrate and a metal case and fixing of the substrate are made and insulation of the metal case and the charged portion is secured, without incurring large-sizing, cost increase, and variations in noise removal performance of the discharge lamp lighting device, and to provide an illumination fixture. SOLUTION: The discharge lamp lighting device is provided with a metal case 1, a substrate 2 of which one face is housed parallel and opposed to the bottom face of the metal case 1, an electronic component 3 which is mounted on the substrate 2, an insulating filler material 5 which is filled from the bottom face of the metal case 1 to at least the tip of the highest one out of the electronic components 3 mounted on one face of the substrate 2, and a metal component 4 of which one end is connected to the bottom face of the metal case 1 and in which a screw hole 4b provided at the other end is screwed to a screw 9 which is inserted in a through hole 2b formed on the ground electrode 2a of the substrate 2, and which connects mechanically the metal case 1 and the substrate 2, electrically connects the ground electrode 2a and the metal case 1, and is higher than the highest one of the electronic components 3 mounted on the one face of the substrate 2.
