W51C is a middle-age (~ 10,000 yrs) Galactic supernova remnant (SNR). A pulsar wind nebula (PWN) candidate, recently detected near the SNR center by Chandra observations, shows a hint of a torus or a jet, which is rather typical feature observed in young PWNe. The remnant itself shows centrally enhanced thermal X-ray emission. While the central emission is positionally coincident with the interaction region with nearby molecular clouds, a possible metal overabundance is reported, which makes the origin of the central X-ray emission puzzling. We propose 110 ks XMM-Newton observations which will be effective to reveal the nature of the PWN candidate, and the origin of the central X-ray emission in W51C.
