Connector terminal and manufacturing method thereof

A connector terminal configured to be electrically connected to an object terminal by making a sliding engagement with a planar surface including the object terminal, the connector terminal comprising:

• a housing configured to slide over the object terminal;
• and
• a spring piece connected to the housing,
• the spring piece including a pressing portion which is configured to be located outside of the housing in a free state of the spring piece, and to move into the housing owing to an elastic deformation of the spring piece when the pressing portion is pressed by the planar surface, and a contact portion which is configured to be located inside of the housing in the free state of the spring piece, and to move out of the housing and make an electric contact with the object terminal as the pressing portion moves into the housing.
