A signal may flow through the wire containing noise in the high frequency region, and a signal wire through which such a signal flows may often be a pair of two wires. The above technique is effective in such a case.

Preferably, the wire connector housing is formed by integrally assembling a first housing and a second housing.

According to the above configuration, the wire connector can be manufactured by a simple method of assembling the first housing and the second housing.

The wire connector housing has two terminal cavities for receiving the two terminals connected to the ends of the two wires, the terminals having a bottom wall on which the wires are placed; And a wire barrel projecting from the side edge of the bottom wall and crimped to the outer periphery of the electric wire, wherein the terminals are disposed such that the bottom walls face each other in each of the two terminal cavities Is preferred.
