This paper describes the resonant connection for constructing a resonant circuit without any external capacitor. Resonance connection is an ingenious circuit connection which makes it possible to utilize the line to line capacitor and inductance for resonance not requiring any additional external capacitors. In this paper, we try to develop a resonance type eddy current sensor using a resonantconnection.As a result, good results have been obtained.Key Words : Eddy current testing, Non-destructive testing, Resonant connection
