(main effect of the first case of manufacturing method)
As described above, in this example, it in the first step, is spread in the inner edge of the peripheral part 15 along lens 10
After the liquid material 30 for coating to complete cycle light shield layer formation, in the second step, with the viscosity and light shield layer 3 with liquid material 30
The corresponding speed such as thickness so that the lens mount 60 of supporting lens 10 is rotated around optical axis L, make liquid material 30 to diameter by centrifugal force
Flowing outward to coat liquid material 30 to peripheral part 15.Therefore, with the case where using the coating head being made of felt type material not
Together, amount variation this case that liquid material penetrates into coating head is not will produce.Therefore, it is possible to which the liquid of light shield layer 3 will be used to form
Object 30 is properly coated on peripheral part, stablizes to the thickness of light shield layer 3.
Also, in the first step, liquid is provided in the inner edge of the peripheral part 15 from liquid material discharge mouth 90 towards lens 10
While shape object 30, the lens mount 60 of holding lens 10 is set to rotate a circle around optical axis L above, therefore can be carried out efficiently first
Process.Also, in the first step, the lens mount 60 of holding lens 10 is set to rotate a circle around optical axis L, therefore pass through the first step
The amount of the liquid material 30 of coating is stablized.Therefore, the thickness of light shield layer 3 is stablized.
Also, since the rotary speed (First Speed) of the lens mount 60 in the first step is than the lens mount in the second step
60 rotary speed (second speed) slowly, therefore can inhibit liquid material 30 to expand to outer peripheral side by centrifugal force in the first step
Exhibition.

Drop etc. disperses to the outside of lens 10.And in this mode, the configuration cover 87 around lens 10 is logical from the inside of the cover 87
Aspirating mechanism 89 is crossed to attract air to upside.Therefore, even if liquid material 30 is dispersed as drop etc. from lens 10, the liquid material
30 can also be attracted to the outside of cover 87.Therefore, it is possible to inhibit the liquid material dispersed 30 to be attached to lens 10.
Also, in 11 side of the one side of lens 10, the air-flow from radially inner side towards outside is generated by air nozzle 81.It is special
It is not, it is high since the terminal part 811 of air nozzle 81 is located in the recess portion 16 surrounded by the cyclic annular inner peripheral surface 18 of lens 10
Effect ground generates the air-flow from radially inner side towards outside.Therefore, even if the liquid material of the flowing of cyclic annular inner peripheral surface 18 along lens 10
30 disperse as drop etc. to the outside of lens 10, also the liquid material dispersed 30 can be inhibited to be attached to lens 10.Also, due to
The opening portion of the recess portion 16 of lens 10 is locally blocked in the lower end 861 of nozzle holder 86 around air nozzle 81, therefore
The lens face 14 that the liquid material 30 dispersed is attached in the recess portion 16 of lens 10 can be reliably suppressed.
Moreover, because the temperature tune that the temperature for being provided with the liquid material 30 to being provided from liquid material discharge mouth 90 is adjusted
Engagement positions 97, therefore the viscosity stabilization of liquid material 30.Therefore, because the coating thickness of liquid material 30 is stablized, thus light shield layer 3
Thickness is stablized.
