In connectors including a housing having a separation wall, an impedance of a portion of a terminal in close proximity to the separation wall is suppressed from dropping excessively. Housings of the connector include a separation wall positioned between adjacent terminals. The separation wall includes a one-side opposing face and an other-side opposing face. Furthermore, the separation wall is formed between the one-side opposing face and the other-side opposing face, and includes a gap portion positioned between the adjacent terminals.
