1. A waveguide-microstrip line converter comprising:
a waveguide having an open end;
a dielectric substrate having a first surface facing the open end and a second surface facing an opposite direction to the first surface;
a ground conductor provided on the first surface and connected to the open end, the ground conductor being provided with a slot in a region enclosed by an end face of the open end; and
a line conductor provided on the second surface,
the line conductor including,
a conversion section adapted to perform power conversion between the line conductor and the waveguide;
a microstrip line provided at a distance from the conversion section in a first direction; and
an impedance transformer provided between the conversion section and the microstrip line, adapted to perform impedance matching between the conversion section and the microstrip line, wherein
a hole is formed in the conversion section.
