An electrical connector with terminals formed therein, at an intermediate location in the terminal width direction, contact portions that come into contact with corresponding contact portions provided in counterpart terminals under contact pressure. Within bounds of the contact portions in the direction of connector insertion and extraction, the above-mentioned terminals have guiding portions configured to guide the corresponding contact portions of the counterpart terminals in the terminal width direction toward the contact portions of the terminals. The guiding portions are formed as inclined faces that extend in a continuous manner to the contact portions while being inclined so as to approach the corresponding contact portions of the counterpart terminals as one moves in the terminal width direction from the side edge locations of the terminals toward the contact portions.
