Abstract: A camera device which includes a holder which retains an optical member therein and a circuit board on which an image sensor is mounted. The holder is joined to the circuit board using an adhesive agent. The circuit board at least partially includes a metallic layer and a resinous layer stacked in a thickness-wise direction of the circuit board. The circuit board has a metallic layer-absent portion in which the metallic layer is partially omitted. The metallic layer-absent portion is located so as to overlap the joint between the holder and the circuit board in the thickness-wise direction of the circuit board, thereby minimizing the transfer of heat of the adhesive agent to the metallic layer. This achieves effective hardening the adhesive agent, which will facilitate the ease with which the camera device is assembled.

Abstract: Provided is a photocurable adhesive with which curing by direct irradiation of laser light is possible with almost no occurrence of surface carbonization and which is capable of satisfactory curing even when the coating thickness is increased. A photocurable adhesive, which is cured by irradiation of laser light, is provided. The curable adhesive contains an epoxy adhesive component, a light-absorbing component for thermal curing of the epoxy adhesive component by absorption of laser light, and an inorganic filler. The content of the light-absorbing component is 0.1 mass % or less. The pre-curing thermal conductivity of the photocurable adhesive is at least 0.2 W/m·K and the post-curing thermal conductivity is at least 0.5 W/m·K.

Abstract: A camera device includes a holder in which an optical member is retained and a circuit board with an image sensor. The circuit board at least includes a stack of a solder resist, a metallic layer, and a resinous layer. A groove or recess is formed in the circuit board to have a depth extending through thicknesses of the solder resist and the metallic layer to expose a portion of an outer surface of the resinous layer. The holder is attached to the exposed portion of the outer surface of the resinous layer using an adhesive agent. An overflow stopper is formed at least round the recess to stop the adhesive agent from flowing outside the recess during a production process, thereby enhancing the degree of joining of the holder and the circuit board, and ensuring the stability in positional relation between the image sensor and the optical member.

Abstract: The lens tube includes a cylindrical barrel, a holder, a cap, and a stress applying portion. The barrel houses at least one first lens. The holder houses an imaging element and is fixed to a substrate. The holder is configured to allow one end of the barrel in an axial direction to be screwed into the holder such that an optical axis of the first lens and an optical axis of the imaging element are aligned with each other. The cap is mountable to the barrel by allowing the other end of the barrel in the axial direction to be screwed into the cap. The stress applying portion is located between the holder and the cap when the barrel is screwed into the holder and the cap, and applies a stress in a direction in which the cap is separated from the holder. The first lens is held and fixed between a first stopper formed on the cap and a second stopper formed in the barrel when the cap is mounted to the barrel.

Abstract: An optical apparatus captures imaging light entering into an imager to acquire an image of an object. The optical apparatus includes a lens module and a support. The lens module is configured by a combination of two or more lenses, captures the imaging light through the lenses, and focuses the captured imaging light on the imager. The support supports the lens module at a position apart from the imager by a predetermined distance, such that the imager and the lenses are aligned on the optical axis, and a focal point of the imaging light is formed on the imager. The support is formed such that an expansion-contraction ratio, at which the support expands or contracts along the optical axis in accord with changes in ambient temperature of the optical apparatus, becomes a first expansion-contraction ratio at which the support expands or contracts so as to cancel a movement of the focal point occurring in the lens module along the optical axis in accord with the changes in ambient temperature of the optical apparatus.
