A connector terminal (10) is provided with a housing (14) for slidably guiding the connector terminal (10) over a conductive surface (92) of a board side terminal (90), and a spring piece (34) supported by the housing (14) so as to resiliently contact the conductive surface (92), and the spring piece (34) is configured in such a manner that a contact portion (48) of the spring piece (34) moves into a path of movement of the conductive surface (92) to serve as a contact portion (48) for electric contact with the board side terminal (90) as a pressing portion (46) of the spring piece is pressed by the conductive surface (92) owing to a sliding movement of the connector terminal (10) relative to the board side terminal (90).
