A connection terminal and a testing jig which are assembled simply and function reliably.A connection terminal used for a connection jig for connecting points used for testing is provided with a small-diameter electrically conductive section and also with a large-diameter cylindrical section disposed so as to surround the small-diameter electrically conductive section. Either the small-diameter electrically conductive section and/or the large-diameter cylindrical section has formed thereon a spring section. The front end surface of the front end of the small-diameter electrically conductive section protrudes from the front end surface of the large-diameter cylindrical section. The front end of the small-diameter electrically conductive section is joined to the front end of the large-diameter cylindrical section. The spring section has a side surface formed by side etching. The front end surface of the front end of the small-diameter electrically conductive section is formed by etching.
