We calculate the hadronic properties of the recently discovered penta-quark baryon state, theta_c particle, by using QCD sum rule technique. The charge of theta_c particle is zero, and theta_c is an anti-charmed pentaquark baryon particle, which consists of five quarks. In this dissertation we calculate the parity of theta_c particle by using interpolating field J= [uCu]d(cd). Our result suggests that the parity of theta_c is positive. This is consistent with the previous result of H. Kim, S. H. Lee, Y. Oh using a different interpolating field.
