An optical device ensuring projection of light over a wide range as well as reduction in size, and a mobile apparatus mounted with the optical device are provided. The optical device ( 100 ) includes a light-projecting unit ( 110 ) and a light-receiving unit ( 120 ). The light-projecting unit ( 110 ) has a projector ( 114 ) and a lenticular sheet ( 112 ) arranged in layers. First and second cylindrical lens arrays having their generatrices orthogonal to each other are formed on the respective surfaces of the sheet ( 112 ). The light-receiving unit ( 120 ) has a light-receiver ( 124 ). The light-projecting unit ( 110 ) and the light-receiving unit ( 120 ) are arranged adjacent to each other in an integrated manner so that the light-receiver ( 124 ) can sense the light emitted from the projector ( 114 ) via the sheet ( 112 ) and then reflected from an object.
