Embodiments of the present invention disclose a detection device for detecting a thickness of a vacuum-evaporated film and a vacuum evaporation apparatus, thereby solving, for example, a problem that a conventional detection device results in excessively high production cost due to frequent replacement of a crystal plate. The detection device includes: a crystal plate, a detection structure provided with an opening corresponding to the crystal plate such that evaporated molecules or atoms are deposited on the crystal plate through the opening; and a filter disposed between the opening and the crystal plate.
