The mounting portion 33b of the lens 33 formed in a spiral shape is engaged with and rotated to the mounting portion 35c of the lens holder 35. The lens unit is configured as described above (see FIG. 8). In the material of the lens holder 35, it is preferable that it is formed of the metal member (for example, aluminum alloy) containing heat dissipation.

In the present embodiment, the lens holder 35 is formed of an aluminum alloy (heat dissipation member), and even if condensation adheres to the lens 33 at the time of a temperature drop in winter or the like, the heat transmitted to the lens holder 35 is transferred to the lens 33. As it transmits, it becomes effective in the prevention of dew condensation. Therefore, it is possible to suppress troubles such as defects in the imaging function that cause condensation and water condensation that enters the electrical system.

In the camera substrate holding member 40, heat is generated from the imaging element 31c. Here, the "imaging element" refers to an IC chip or the like which converts and processes an optical image around the vehicle incident through a lens of a camera unit into an electric signal, and can store such an electric signal in a storage means such as a ROM or a RAM.

This grounding member 53b is grounded to the inner wall surface 32f of the camera body 32.

The ground member 53b of the shield plate 50 is grounded to the inner wall surface 32f of the camera body 32, so that earth can be taken. By taking the earth, the potential of the camera body 32 is stabilized, thereby reducing the occurrence of noise in the entire vehicle-mounted camera. In other words, by installing the earth function on the shield plate 50, there is no need to separately install an earth wire or the like for taking the earth. This contributes to the reduction of the number of parts of the on-board camera structure.

As shown in Fig. 6 (d), the slit 52b includes an opening having a size that can be engaged with the slit engaging portion 31g of the connector side substrate 31b substantially in the vicinity of the center member at a predetermined distance from the base end 51b of the side plate portion 52. do. By engaging the slit engaging part 31g of the connector side board | substrate 31b with such a slit 52b, the temporarily fixing of the connector side board | substrate 31b is attained. In the state which temporarily fixed the connector side board | substrate 31b, the predetermined space is formed between the shield plates 50. As shown in FIG. For this reason, height adjustment in the case of providing another member on the shield plate 50 is attained.

That is, as the configuration of the on-vehicle camera 10, a plurality of members are placed on the shield plate 50 in the order of the camera substrate 31, the lens holder 35, the lens 33 and the camera body 32, it is necessary to adjust the height between each member.
