A connector including a pair of first terminals, a second terminal, a third terminal, and a body. The first terminals are differential signal terminals in spaced juxtaposition to each other. The second terminal is located on one side relative to and in spaced relation to one of the first terminals. The third terminal is located on the other side relative to and in spaced relation to the other first terminal. The body holds the terminals at least partially. The body includes a first portion between the first terminals, a second portion between the one first terminal and the second terminal, and a third portion between the other first terminal and the third terminal. The second portion has a second void, which extends from the one first terminal to the second terminal. The third portion has a third void, which extends from the other first terminal to the third terminal.
