Connection terminal and terminal connection structure

A connection terminal comprising:

• a base portion having a flat shape;
• a folded portion which is folded back from a rear end of the base portion in a terminal fitting direction and extends toward a front side in the terminal fitting direction;
• a rise portion that is provided at an intermediate portion of the folded portion in the terminal fitting direction and rises in a direction away from the base portion;
• and
• a terminal contact portion that extends from the rise portion toward the front side in the terminal fitting direction and is elastically deformable in the direction away from the base portion at a position facing the base portion,
• wherein the connection terminal is configured to receive a base portion of a counterpart connection terminal having a same configuration as that of the connection terminal such that the base portion of the counterpart connection terminal is inserted and elastically sandwiched between the base portion and the terminal contact portion of the connection terminal while the counterpart connection terminal is vertically inverted with respect to the connection terminal.
