Three-alpha resonance excited states has been theoretically explored by means of the α+α+α microscopic cluster model. The resonance parameters is determined by employing the Complex Scaling Method (CSM). Our model space is extended by including higher partial waves than the RGM+CSM calculation by Pichler1. Our model has given the third 0+ state at 4~5MeV above the three-body threshold but the broad 0+ state, which was recently reported experimentally and overlapping with the 2+ state2, has not been localized between the second and the third 0+ states. On the other hands, our model has given the second 2+ state about 2MeV and the third at 4~5MeV.
