PROBLEM TO BE SOLVED: To provide a spring connector 26 of a very simple configuration wherein accuracy in fitting position is high. SOLUTION: A wire material having conductivity and elasticity is wound as a coil, and a step 20b is provided in the middle section in the axial direction of the coil to form a small-diameter coil 20c axially, which is to be a spring terminal 20. A hole 22a is opened on a circuit board 22, and a circuit conductor 22a is provided on the inner peripheral surface of the hole 22a. The diameter of small-diameter coil 20c is reduced and press-fitted in the hole 22a so as to elastically contact the circuit conductor 22a, and the spring terminal 20 is electrically connected to the circuit conductor 22a provided on the circuit board 22 through the small-diameter coil part 20c, thus constituting a spring connector 26.
