Claim 0:
1. A camera module, comprising:
a lens holder, comprising:
a holder body; and
a lens barrel disposed on the holder body;

an adhesive layer; and
an optical filter connected to the holder body through the adhesive layer,
wherein the holder body comprises a first surface away from the lens barrel and a second surface opposite to the first surface, the first surface defines a groove, the groove comprises a first bottom surface, the first bottom surface defines a recess, the recess comprises a second bottom surface, the second bottom surface defines an air escape hole;
wherein a cross-sectional size of the air escape hole is less than a cross-sectional size of the recess;
wherein the optical filter is received in the groove, the adhesive layer is disposed between the optical filter and the first bottom surface of the groove, thereby connects the optical filter to the first bottom surface;
the holder body is square shaped, the lens barrel is cylindrical shaped, an orthogonal projection of the lens barrel on the holder body is in a center region of the second surface, a center of the orthogonal projection of the lens barrel overlaps with a center of the holder body, and the recess is disposed at a corner of the holder body away from the center of the orthogonal projection, and
the recess is entirely rectangular shaped and extends diagonally along the first bottom surface, the recess has a first end and a second end opposite to the first end, the first end is closer to the center of the orthogonal projection with respect to the second end, the first end is spaced apart from the orthogonal projection, the air escape hole is disposed at the first end.
