Flat conductor electric connector

A flat conductor electric connector configured such that a flat conductor extending in a front-back direction is inserted and connected forward to the flat conductor electric connector, comprising:

• a plurality of terminals arrayed in a flat conductor width direction which is a terminal alignment direction;
• a housing holding the plurality of terminals;
• and
• a slider,
• wherein the housing includes a receiving portion configured to receive the flat conductor from a back and a locking protruding portion configured lockable to a locking target portion of the flat conductor from the back,
• the locking protruding portion is positioned in the receiving portion, and protrudes upward in an upper-lower direction which is a flat conductor thickness direction,
• the slider is attached to the housing so as to move in the front-back direction between a retreat position and an advance position, and includes a first abutting portion configured to be able to abut on an upper surface of the flat conductor at the advance position and a second abutting portion configured to abut on a lower surface of the flat conductor at the retreat position,
• the second abutting portion is provided on a front side with respect to the first abutting portion, and
• an upper end of the second abutting portion is, in the upper-lower direction, at a position identical to that of an upper end of the locking protruding portion or a position higher than the upper end of the locking protruding portion.
