Disclosed is an improved board-surface mounting type electric connector whose pin terminals are designed to be soldered to a printed circuit pattern by their tail sections. Each tail section is composed of a soldering portion, an intermediate stepwise joint and a non-soldering portion. The soldering portion of the tail section is laid on the printed board, and the non-soldering portion is laid on an isolation wall at a level higher than the printed board, thus leaving space between the printed board and the non-soldering portion available for printing desired circuit patterns. Connector housing may have at least one stopper to abut on the upper surface of each soldering portion for preventing it from rising, thereby keeping each soldering portion stable in position.
