    Abstract: The invention provides a dome cover, a camera device, an injection molding die, and an injection molding method in which generation of a weldline is suppressed and deterioration of an acquired image is suppressed. In one aspect of the invention, a dome cover is a dome cover that covers a camera. The dome cover includes a curved section having a curved shape and a skirt section having a cylinder shape and has a top section at the curved section and an opening end section at the skirt section. The thickness of the dome cover is largest at the top section and smallest at the opening end section, and continuously decreases from the top section toward the opening end section. The inner diameter and the outer diameter of the dome cover continuously increase from the top section toward the opening end section.

    Abstract: In order to produce high-quality optical elements stably at all times without the flow of molten resin inside an injection molding cavity being hindered by the protrusion of the outer peripheral edge of a lens after compression molding, a cavity formed when a pair of molds for molding is closed is provided with: an optical-function-part molding cavity (27); an annular connection-part molding cavity (28) connected to the outer peripheral edge of the optical-function-part molding cavity; and an edge-part molding cavity (29) connected to the outer peripheral edge of the connection-part molding cavity. In a compression molding step, a protrusion part is formed by making a portion of a compression molding material bulge out from the connection-part molding cavity into the edge-part molding cavity (29). In an injection molding step, the molds are filled by injecting an injection molding material into the edge-part molding cavity (29). The resin of the protrusion part that has protruded from the connection-part molding cavity into the edge-part molding cavity (29) is biased toward one direction of the molds so as not to hinder the flow of the injection molding resin. The biased amount is set such that, when the cross section of the resin that has protruded into the edge-part molding cavity (29) is divided by a perpendicular bisector (L) that is perpendicular to the optical axis and that divides the thickness of the connection part in half, the cross-sectional area on the biased side includes greater than or equal to 60% of the cross-sectional area of the protruded resin.

    Abstract: A lens manufacturing method including a holding step of holding a lens in a lens holding fixture, and a machining step of machining a surface to be machined in the held lens. A reverse surface of the surface to be machined is machined into a non-planar shape with a first surface shape error. A lens holding surface of the lens holding fixture is machined into the same shape as the non-planar shape with a second surface shape error smaller than the first surface shape error. In the holding step, the reverse surface is brought into surface contact with the holding surface in imitation of the holding surface to correct the shape of the lens such that the reverse surface runs along the holding surface. In the machining step, the surface to be machined is machined in a state where the correction has been made by the holding step.
