A female terminal comprising: a conductive, tube-shaped main body comprising a bottom plate, a top plate, and side plates (13, 14); and an elastic contact plate supported inside the main body, possessing conductivity and elasticity, and extending from one opening into which a male terminal is to be inserted, toward another opening; wherein the elastic contact plate comprises: a first section that faces the bottom plate of the main body and is separated from the bottom plate; a first contactor that is positioned on the opening side of the first section and contacts the bottom plate; a second section that extends in an arch shape toward the another opening from the first contactor; and a second contactor that is positioned on the another opening side of the second section and contacts the bottom plate; characterized in that the female terminal further comprises protrusions (L1, L2) that protrude in respectively opposing directions from the side plates (13, 14) and provided closer to the one opening than to the another opening, the protrusions (L1, L2) pressing a surface of the first section facing the top plate when the male terminal makes contact with the elastic contact plate; the main body supports the elastic contact plate so that the first contactor and the second contactor are able to slide on the bottom plate; the first section has a shape in which a section facing the bottom plate is removed, is formed to be thinner than the other sections of the first section of the elastic contact plate, and is separated from the bottom plate; and the first contactor includes a curved section (220, 220A) along a long axis of the elastic contact plate and the curved section (220, 220A) linearly and slidably comes into contact with the bottom plate at a line orthogonal to the long axis. a conductive, tube-shaped main body comprising a bottom plate, a top plate, and side plates (13, 14); and an elastic contact plate supported inside the main body, possessing conductivity and elasticity, and extending from one opening into which a male terminal is to be inserted, toward another opening; wherein the elastic contact plate comprises: a first section that faces the bottom plate of the main body and is separated from the bottom plate; a first contactor that is positioned on the opening side of the first section and contacts the bottom plate; a second section that extends in an arch shape toward the another opening from the first contactor; and a second contactor that is positioned on the another opening side of the second section and contacts the bottom plate; a first section that faces the bottom plate of the main body and is separated from the bottom plate; a first contactor that is positioned on the opening side of the first section and contacts the bottom plate; a second section that extends in an arch shape toward the another opening from the first contactor; and a second contactor that is positioned on the another opening side of the second section and contacts the bottom plate; characterized in that the female terminal further comprises protrusions (L1, L2) that protrude in respectively opposing directions from the side plates (13, 14) and provided closer to the one opening than to the another opening, the protrusions (L1, L2) pressing a surface of the first section facing the top plate when the male terminal makes contact with the elastic contact plate; the main body supports the elastic contact plate so that the first contactor and the second contactor are able to slide on the bottom plate; the first section has a shape in which a section facing the bottom plate is removed, is formed to be thinner than the other sections of the first section of the elastic contact plate, and is separated from the bottom plate; and the first contactor includes a curved section (220, 220A) along a long axis of the elastic contact plate and the curved section (220, 220A) linearly and slidably comes into contact with the bottom plate at a line orthogonal to the long axis.
