A connector, with which an electrical wire is attachable, is connectable with a mating connector which has a mating contact portion. The connector comprises a housing and at least one terminal. The housing is provided with a support. The support has a receiving portion. The receiving portion is configured to receive a part of the electrical wire. The at least one terminal has an insulation displacement connection (IDC) portion, a contact portion, a supporting portion and a coupling portion. The IDC portion is configured to be insulation-displacement connected with the electrical wire. The support is positioned between the IDC portion and the supporting portion in a first predetermined direction. The coupling portion couples the IDC portion and the supporting portion with each other. The coupling portion has a neighboring portion. The neighboring portion neighbors to the support in a second predetermined direction perpendicular to the first predetermined direction.
