An on-vehicle camera apparatus capturing an image in front of a vehicle includes: a camera module outputting image data and a control circuit board. The camera module includes an optical element that refracts incident light so as to diverge or focus the incident light, and an image sensor element in which incident light transmitted through the optical element forms an image. The control circuit board executes, based on the image data outputted by the camera module, a recognition process recognizing a state in front of the own vehicle, and also executes at least two vehicle control processes among a headlight control process, a forward collision preventing process and a lane departure warning process, as a result of the recognition process. According to the on-vehicle camera apparatus, a resin-made lens is used for the optical element.
