The present invention is directed to a connection terminal and a circuit board module including the connection terminal. The connecting terminal includes a substrate which is arranged in a quadrangular shape and is arranged on the PCB; a first guide including a first vertical portion bent perpendicularly to the substrate at a first edge of the substrate and a first horizontal portion bent perpendicularly from the first vertical portion along an inward direction to be parallel to the substrate; a second guide member including a second vertical portion bent perpendicularly to the substrate at a second edge and a second horizontal portion bent from the second vertical portion along an inward direction to be parallel to the substrate; and a spring comprising a bent portion disposed in one of the remaining edges except for the first and second edges and bent perpendicularly to the substrate, a double bent portion bent from the bent portion into a double helix shape and a contact portion provided so as to protrude upwardly from the double bent portion to be connected to the terminal apparatus on the opposite side of the PCB.
