To provide an electrical connection terminal and an electrical connector which can be connected surely, even to a flat circuit body, such as one having a flat conductor with small arrangement pitches, and in which precise and expensive bending caulking means of piercing piece is not required.

This electric connection terminal 12 is constituted so that it has a terminal penetrating conductive part 22 and a terminal-receiving part 24, that pinch-conduct a flat circuit body 20 by fitting each other, while pinching the flat circuit body 20 in between, in which the terminal piercing conductive part 22 is provided with a terminal base part 30 and the penetrating pieces 32 that are protruded on the terminal base part 30 arranged in one piece or in a plurality of pieces in a row at a prescribed spacing, and which penetrated through the flat conductor 26 of the flat circuit body 20, while the terminal receiving part 24 is provided with a receiving groove 34 holding the piercing pieces 32 that are penetrated through the flat circuit body 20.
