PROBLEM TO BE SOLVED: To provide a camera apparatus capable of imaging the field of view in the direction almost orthogonal to the imaging optical axis so that the range of field of view that is imaged is not narrowed, nor an invalid image portion is caused within the range of field of view that is imaged. SOLUTION: In the camera apparatus 1, its prisms 13 and 14 are so arranged that their back surfaces 13B and 14B are directed toward an imaging lens 9 while their side surfaces 13L and 14R are directed toward left/right field of view. Incident light CL and CR on the side surfaces 13L and 14R is internally reflected twice between the side surfaces 13R and 14L on the anti-field of view side and the side surfaces 13L and 14R on the field of view side, and emitted from the back surfaces 13B and 14B, and then focused on an imaging element 7 through the imaging lens 9. On all surfaces of the side surfaces 13R and 14L, reflecting films 20R and 21L for totally reflecting light CL and CR that enters the inside surfaces are provided. On such regions where the light CL and CR that enter the inside surfaces do not totally reflect among the side surfaces 13L and 14R, films 20L and 21R that totally reflect the light CL and CR entering the inside surfaces of the regions are provided.
