It is worth noting that the electrical connection assembly 3-1021 penetrates the body 3-1020 of the base 3-102, and the electrical connection assembly 3-1021 is electrically independent of the body 3-1020 of the base 3-102. In addition, when viewed along the direction perpendicular to the optical axis 3-O (for example, the X-axis), the base 3-102, the integrated package substrate 3-110, and the photosensitive element 3-120 do not overlap each other.
Similar to the photosensitive module 3-300, the first heat dissipation structure 3-HD1 of the photosensitive module 3-400 also is in direct contact with the photosensitive element 3-120 and the base 3-102, and when viewed along the optical axis 3-O, the area of the first heat dissipation structure 3-HD1 is less than or equal to the area of the photosensitive element 3-120.
