Dome cover, camera device, injection molding die, and injection molding method

A camera device comprising:

• a camera;
• and
• a dome cover that covers the camera, the dome cover comprising:
• a curved section having a curved shape;
• and
• a skirt section having a cylinder shape, the skirt section provided at one end of the dome cover,
• wherein a top section is provided at the curved section and an opening end section is provided at the skirt section, the top section provided at another end of the dome cover,
• wherein a thickness of the dome cover is largest at the top section and is smallest at the opening end section and continuously decreases from the top section toward the opening end section,
• wherein an inner diameter and an outer diameter of the dome cover continuously increase from the top section toward the opening end section,
• wherein the camera is capable of capturing an image including a boundary between the curved section and the skirt section, and
• wherein a thickness T of the dome cover is expressed by the following formula in a case where a distance along an outer periphery of the dome cover from the top section to the opening end section is defined as x, a thickness of the dome cover at the opening end section is defined as t1, and a monotonously decreasing function is defined as f(x),
• T=t1+f(x),
• and wherein a thickness of opening end section is 85% or more and 90% or less than a thickness of the top section.
