Connector with pair of terminals and coupling portion

A connector, comprising:

• a pair of terminals comprising a first terminal and a second terminal, each of which includes a first connecting portion to which a first connection target object is connected, a second connecting portion to which a second connection target object is connected, and a coupling portion that couples together the first connecting portion and the second connecting portion, the pair of terminals being arranged with a spacing therebetween and a differential signal being transmitted via the pair of terminals;
• a dielectric portion that holds the pair of terminals;
• and
• a low-dielectric constant portion that has a lower relative dielectric constant than a relative dielectric constant of the dielectric portion and that is interposed between the coupling portion of the first terminal and the coupling portion of the second terminal,
• wherein a spacing between the coupling portion of the first terminal and the coupling portion of the second terminal is smaller than at least one of a spacing between the first connecting portion of the first terminal and the first connecting portion of the second terminal or a spacing between the second connecting portion of the first terminal and the second connecting portion of the second terminal, and
• wherein an intermediate portion of the coupling portion of the second terminal comprises a first portion that is substantially parallel to the coupling portion of the first terminal, a second portion that extends from the first portion toward the coupling portion of the first terminal such that an entire width of the second portion approaches the coupling portion of the first terminal, and a third portion that extends from the first portion such that an entire width of the third portion withdraws from the coupling portion of the first terminal.
