Coupling between terminals can be properly arranged and the effect of crosstalk and noise can be surely and significantly reduced. Including a pair consisting of a first terminal and a second terminal, each of the first terminal and the second terminal includes a contact part extending in the anteroposterior direction, an upper plate and a lower plate extending in the vertical direction, a link section extending in the lateral direction and linking up with the upper plate and the lower plate, the contact part of the first terminal is opposite the contact part of the second terminal in the vertical direction, the upper plate of the first terminal is opposite the upper plate of the second terminal in the lateral direction, the lower plate of the first terminal is opposite the lower plate of the second terminal in the lateral direction, and the positional relationship between the upper plate of the first terminal and the upper plate of the second terminal in the lateral direction is opposite the positional relationship between the lower plate of the first terminal and the lower plate of the second terminal in the lateral direction.
