Intervening connection apparatus capable of easily and accurately positioning a conductor

In a connection apparatus for electrically connecting two connection objects to each other, a frame is disposed between the connection objects and has two surfaces faced to the connection objects, respectively. An elastic member penetrates the frame and has two end portions protruding from the two surfaces, respectively. A conductor is coupled with the elastic member and extending between the two end portions. A positioning member is formed as a member separate from the elastic member and positioning the elastic member with respect to the frame.
