Abstract: A braider includes: a plurality of cylindrical bobbins around which flat foil yarns are wound so as not to be inverted; a plurality of carriers to which the bobbins are rotatably attached, the plurality of carriers being configured to feed out the flat foil yarns from the bobbins; a core material supply mechanism configured to supply a core material to be placed inside the outer conductor; a waveguide take-out mechanism configured to take out the flexible waveguide after the outer conductor is formed; and a carrier movement determination mechanism configured to determine movement of the carriers so that there are always three or more cross points formed by the individual flat foil yarns with other ones of the flat foil yarns in an enlarged portion before the flat foil yarns form a braided shape.

Abstract: A connection structure of a waveguide includes a rod-like dielectric, and an outer conductor. A three-dimensional component includes a connection surface, an insertion hole, and a corner which forms an opening edge of the insertion hole over an entire circumference on the connection surface, the connection surface at least partially including a conductive region to which a connection enlarged portion of the outer conductor is connected, the insertion hole having conductivity over an entire circumference of an inner surface, the corner having conductivity and being conducted with the inner surface of the insertion hole. In a state where the waveguide and the three-dimensional component are connected with each other, the connection enlarged portion is electrically conducted with the inner surface of the insertion hole through electrical connection with the connection surface and the corner, and smooth connection is made at the corner.
