Abstract
A waveguide includes: a first tubular waveguide path that transmits electromagnetic waves having a predetermined wavelength; and a stub that is formed such that a depth thereof becomes a quarter of the predetermined wavelength, an open end of the stub making internal contact with a contour line, and the contour line being spaced apart from an inner wall part of one end of the first tubular waveguide path in a radially outward direction by only a quarter of the predetermined wavelength.
