The utility model relates to the technical field of millimeter wave frequency band filters, and discloses a W-band E-plane metal diaphragm waveguide band-pass filter, which comprises a metal diaphragm, a dielectric substrate and a rectangular waveguide resonant coupling cavity, the dielectric substrate is sequentially provided with a substrate top layer and a substrate bottom layer from top to bottom along a Z axis, and four rows of metalized through holes are further arranged on the dielectric substrate. The top metal layer and the bottom metal layer are connected through four rows of plated-through holes, the metal diaphragms are arranged on the dielectric substrate, and the rectangular waveguide resonant coupling cavity surrounds the dielectric substrate. According to the technical scheme, the requirements of different sizes and insertion loss filters are met by changing the length of the metal diaphragms, the distance between the metal diaphragms and the material of the dielectric substrate, the design pr
