PROBLEM TO BE SOLVED: To provide a high-frequency line/waveguide converter having high conversion efficiency of transmission between a high-frequency line and a waveguide. SOLUTION: The high-frequency line/waveguide converter is provide with the high-frequency line 1 consisting of a line conductor 3 formed on the top surface of a dielectric layer 2 and a coplanar grounding conductor layer 4 formed so as to surround one end of the line conductor 3 on the top surface of the dielectric layer 2; a slot 5 formed on the conductor layer 4 so as to cross the one end of the line conductor 3 at right angles and electromagnetically coupled with the line conductor 3; a grounding conductor layer 8 having an opening 11 formed so as to surround the slot 5 in plan view on the inner layer or the bottom surface of the dielectric layer 2; and a shield conductor section 7 formed so as to surround the one end of the line conductor 3 and the opening 11 in plan view, and to electrically connect the conductor layer 4 to the conductor layer 8. In this converter, a short circuit section 12 for dividing the opening 11 into two is formed on a part positioned immediately below the opening 11 of the line conductor 3.
