0.15mm, the side wall of the first light hole 682 are equal to or more than 0.325mm with respect to the distance at the edge of photo-sensitive cell 40.In this way, can
The connection of installation and conductive connecting 80 for photo-sensitive cell 40 provides enough operating spaces, and avoids photo-sensitive cell 40 with leading
The influence that the manufacture of electric connection line 80 and alignment error are brought.
As shown in figure 1, in one embodiment, internal diameter of second light hole 684 close to the side of the first light hole 682 is more than the
The internal diameter of one light hole 682, step surface is formed between the second light hole 684 and the first light hole 682.In this way, it can ensure to be somebody's turn to do
Material usage is saved while the part that packaging body 60 is placed thereon with certain supporting role to support.Also, work as packaging body
When installing other parts by glue on 60, the glue overflowed between part and upper surface 62 can flow on step surface and can keep away
Exempt from glue to be flowed directly on photo-sensitive cell 40 and damage photo-sensitive cell 40.
It is appreciated that step surface can be also not provided between the first light hole 682 and the second light hole 684, such as Fig. 2 institutes
Show, in another embodiment, internal diameter of second light hole 684 close to the side of the first light hole 682 is equal to the first light hole 682
Internal diameter.
As shown in Fig. 1~Fig. 2, a kind of camera module (not shown) of this preferred embodiment, including above-mentioned photosensory assembly
100, in addition to optical module.
Wherein, optical module includes camera lens and is sheathed on the voice coil motor of camera lens.Specifically, voice coil motor is located at packaging body
On 60, camera lens includes the multiple eyeglasses being stacked.Light is incident from camera lens and reaches the photosurface 42 of photo-sensitive cell 40, photosensitive
Face 42 converts optical signals into electric signal.
Above-mentioned camera module, because its photosensory assembly 100 included has larger thang-kng amount, therefore the camera module has
There are preferable image quality and less volume, the smart machine for being advantageous to be provided with the camera module is ensureing image quality
Develop simultaneously to lightening direction.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
