Zusammenfassung:	Provided is an illumination device capable of preventing a reflection sheet in the periphery of a light-emitting element from being raised while minimizing the instability in the fixture of a diffusing lens. The illumination device (10) comprises a light-emitting element (11), a mounting substrate (12), a diffusing lens (13), and a reflection sheet (14) having a through-hole (14a). The diffusing lens includes a lens portion (13a) for diffusing light, and a fixed portion (13b) to be fixed to the mounting substrate. An engaging portion (13e) that sandwiches the reflection sheet between the engaging portion and the mounting substrate is formed in the fixed portion. La présente invention concerne un dispositif d'éclairage capable d'empêcher qu'une feuille réfléchissante à la périphérie d'un élément électroluminescent soit soulevée tout en réduisant l'instabilité de la fixation d'une lentille de diffusion. Le dispositif d'éclairage (10) comprend un élément électroluminescent (11), un substrat de montage (12), une lentille de diffusion (13) et une feuille réfléchissante (14) comportant un trou traversant (14a). La lentille de diffusion comprend une partie lentille (13a) permettant de diffuser de la lumière, et une partie fixe (13b) devant être fixée au substrat de montage. Une partie mise en prise (13e) qui intercale la feuille réfléchissante entre la partie mise en prise et le substrat de montage est formée dans la partie fixe.
