Provided is a low-leakage automatic adjustable diplexer including a body, a thin plate and two resonant regulators. The body has therein cuboid waveguide channels each having a feeding portion, a reception port portion, a transmission port portion, a fitting portion, a first filtering portion, a second filtering portion, first E/H conversion units connected to two ends of the first filtering portion, respectively, and second E/H conversion units connected to two ends of the second filtering portion, respectively. The thin plate is clamped inside the body. The resonant regulators each have a plurality of frequency disturbance elements adjustably protruding into the first and second filtering portions. Given the E/H conversion units and the frequency disturbance elements penetratingly disposed on the H-side sidewall of the cuboid waveguide cavity, it is unnecessary for the cuboid waveguide channels to undergo any processing process for forming therein any protrusion-style insulation walls, thereby attaining low leakage.
