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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The connection terminal according to claim 1, wherein the terminal contact portion comprises a contact portion which is provided at an intermediate portion of the terminal contact portion in the terminal fitting direction and which is bent so as to protrude toward the base portion. ### Claim 3 (depends on 1) The connection terminal according to claim 1, wherein the base portion comprises a contact protrusion that protrudes toward the terminal contact portion from a surface of the base portion facing the terminal contact portion. ### Claim 4 (depends on 1) The connection terminal according to claim 1, wherein the terminal contact portion comprises a plurality of divided pieces formed by dividing the terminal contact portion in a width direction intersecting the terminal fitting direction by a slit formed between adjacent ones of the plurality of divided pieces and extending from a front end of the terminal contact portion along the terminal fitting direction. ### Claim 5 (depends on 1) The connection terminal according to claim 1, wherein the terminal contact portion comprises a plurality of divided pieces formed by dividing the terminal contact portion in a width direction intersecting the terminal fitting direction by a slit formed between adjacent ones of the plurality of divided pieces and extending from a front end of the terminal contact portion along the terminal fitting direction, wherein the terminal contact portion comprises a plurality of contact portions which are provided at intermediate portions of the plurality of divided pieces in the terminal fitting direction, respectively, and which are bent so as to protrude toward the base portion, and wherein the plurality of contact portions are provided at different positions along the terminal fitting direction, respectively. ### Claim 6 (depends on 1) A terminal connection structure comprising: a first electric wire connection portion in which an end of a first electric wire is electrically connected to a folded portion of a first connection terminal having a same configuration as that of the connection terminal according to claim 1; and a second electric wire connection portion in which an end of a second electric wire is electrically connected to a folded portion of a second connection terminal having a same configuration as that of the connection terminal according to claim 1, wherein a base portion of the second connection terminal is inserted and elastically sandwiched between a base portion and a terminal contact portion of the first connection terminal while the second connection terminal is vertically inverted with respect to the first connection terminal, and the base portion of the first connection terminal is elastically sandwiched between the base portion and a terminal contact portion of the second connection terminal. ### Claim 7 (depends on 1) A connection terminal comprising: a plurality of connection terminal portions, each of the plurality of connection terminal portions 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; and a coupling portion provided between the base portions of adjacent ones of the plurality of connection terminal portions, wherein a base portion of the connection terminal according to claim 1 is inserted and elastically sandwiched between the base portion and the terminal contact portion of one of the plurality of connection terminal portions while the connection terminal according to claim 1 is vertically inverted with respect to the plurality of connection terminal portions.
