A connection structure of a coaxial harness includes a coaxial harness, a ground bar, and a substrate. The coaxial harness includes a plurality of coaxial cables lined up. The coaxial cable includes a center conductor, an inner insulator, an outer conductor, and a jacket. The inner insulator and the outer conductor and the jacket are placed at an outer side of the center conductor in an order of the inner insulator, the outer conductor, and the jacket. The ground bar sandwiches a plurality of the outer conductor exposed at an end terminal part of the coaxial harness. The substrate is provided with a ground bar connection terminal and a center conductor connection terminal group. The ground bar connection terminal is connected with the ground bar. The center conductor connection terminal group includes an alignment of a center conductor connection terminal connected respectively to the center conductor. Here, a plurality of the coaxial harnesses are stacked. In addition, a plurality of the center conductor connection terminal groups are provided to the substrate in a direction moving away from the ground bar connection terminal. The plurality of the center conductor connection terminal groups form a plurality of layers. Further, the ground bar is electrically connected to the one ground bar connection terminal. The ground bar is provided at an end terminal part of the plurality of coaxial harnesses. The center conductor of the coaxial harness, provided at a first layer close to the substrate, is connected to a first group of the center conductor connection terminal group, formed at a region closest to the ground bar connection terminal. Moreover, the center conductor of the coaxial harness, stacked on the coaxial harness provided at the first layer, is connected to the center conductor connection terminal group, provided at a next layer side with respect to the first group of the center conductor connection terminal group. |
