The purpose of the present invention is to obtain an illumination lamp which efficiently uses the light emitted from a light source as emitted light of the illumination lamp, and which improves light-emission efficiency. This illumination lamp is characterized by being provided with: a light source module 3 which has a long shape, and in which a light source 4 is provided to a surface parallel to the length direction; and a cover 2 provided with a translucent cylindrical part 21 which has a long shape, and covers the emission-side surface of the light source module 3 from which light of the light source 4 is emitted, and holding protrusions 22 which protrude towards the inside of the cylindrical part 21, have emission-side flat surfaces 22a with a higher reflectance than the cylindrical part 21, and have device-side flat surfaces 22b that come into contact with the light source module 3.
