Contactor and connector having the same

The invention provides a contactor and a connector having the same. The contactor has a simple structure and can realize miniaturization in the longitudinal spacing direction and the traverse (width) direction of the connector, the connector is not damaged in miniaturization, and stable contact (connection) reliability can be obtained. The contactor (20) includes a contact portion that is configured to come into contact with a counterpart object, a connecting portion (209) connectable to an object to be connected, a main body portion (201) having two side walls (202) and a joining wall (203) that joins the side walls (202), the main body portion having a substantially U-shaped cross section, first and second contact pieces (204, 205) protruding from the two side walls (202) and extending along a direction of mating with a counterpart object, and first and second contact portions (206, 207) disposed at free end parts of the first and second contact pieces (204, 205), respectively. The first and second contact
