PROBLEM TO BE SOLVED: To provide a high-frequency line waveguide converter with a high conversion efficiency. SOLUTION: The high-frequency line waveguide converter includes a high-frequency line 1 comprising a line conductor 3 formed on the upper face of a dielectric layer 2 and a same plane grounding conductor layer 4; slots 5 formed to the same planar grounding conductor layer 4 in a way of being orthogonal to one-ends of the line conductor 3; a grounding conductor layer 9 formed to the inner layer or the lower side of the dielectric layer 2; shielding conductors 7 for surrounding the slots 5 in planar perspective view and electrically connecting the same plane grounding conductor layer 4 and the grounding conductor layer 9; and a waveguide 6 electrically connected to the grounding conductor layer 4; and if the distance between the coplanar grounding conductor layer 4 and the grounding conductor layer 9 is L, the interval between the shielding conductors 7 at both sides of the line conductor 3 and adjacent to the line conductor 3, respectively is G, and the effective wavelength of a high-frequency signal transmitted through the high frequency line 1 isλ, then equation (G+2×L)≤λ/2 holds.
