Provided is a highly decorative lighting device using a lenticular lens sheet. This lighting device (10) is provided with a lenticular lens sheet (11) and an LED light source (12). The lenticular lens sheet (11) is curved in the X-direction and a convex surface (11A) side thereof is formed in a concave shape. The LED light source (12) is located on the convex surface (11 A) side of the lenticular lens sheet (11). First and second reflected components (R1, R2), which respectively come from first and second bright spots of a plano-convex cylindrical lens (14) by reflection of light emitted from the LED light source (12), are respectively incident to left and right eyes (LE, RE) of an observer observing the lighting device (10) The observer observes a virtual image (K1) as though an illuminant is present at the intersection of the first and second reflected components (R1, R2).
