Document Type and Number:
Japanese Patent JP7424415
Kind Code:
B2
Abstract:
To provide: a light shielding plate that enables a decrease in a light amount of light which is reflected on a side surface, where a hole is partitioned, so as to be transmitted through th hole; a camera unit; and an electronic apparatus.SOLUTION: A light shielding plate 10 comprises a hole 10H. The hole 10H includes: a first hole 10H1 that has a rear surface opening H1R on the rear surface 10R and has a shape tapering from the rear surface 10R toward the front surface 10F; and a second hole 10H2 that has a front surface opening H2F, larger than the rear surface opening H1R, on the surface 10F and has a shape tapering from the front surface 10F toward the rear surface 10R to connect to the first hole 10H1. A central opening HC is an opening on a side opposite to the rear surface opening H1R, of the openings included in the first hole 10H1. Under an imaging condition that a depth of field is 0.4 μm, a maximum width of the light shielding plate 10 in focus is 7.0 μm or less, when an edge of the central opening HC is imaged along a radial direction of the central opening HC in a state in which the edge of the central opening HC is in focus.SELECTED DRAWING: Figure 2
