description The invention relates to a method for manufacturing a waveguide device (1), comprising a step of producing, by additive manufacturing, a semi-finished metal core (2) comprising side walls (20) having outer surfaces (21) and inner surfaces (22), the inner surfaces (22) defining an internal waveguide opening (5). The manufacturing method further comprises a step of chemically polishing the metal core (2) in order to reduce the thickness of said side walls (20) by an ablation thickness equal to at least two times a roughness (Ra) of the metal core (2) before polishing, so as to obtain the waveguide device. The invention also relates to a waveguide device (1) obtained according to the above-mentioned method.
