The present application discloses an imaging camera, including: a lens holder with an accommodation space; a lens unit group received in the accommodation space; and a supporting frame. The supporting frame includes a top wall having a first surface facing an object side of the imaging camera, a second surface opposite to the first surface, and a third surface connecting the first surface to the second surface. The imaging camera further includes an aperture formed in the third surface; a glue-in opening formed in the first surface; and a glue-out opening formed in the third surface and communicated with the glue-in opening. By virtue of the invention, the pressing ring can be affixed to the lens holder by the glue flowing from the glue-in opening to the glue-out opening via the first and second channels.
