G349.7+0.2 is one of the brightest supernova remnants detected in infrared waveband. The bright infrared emission is probably related to the interaction with molecular cloud. Indeed, the near infrared H2 narrow band image shows shock-heated warm gas of the molecular cloud whose coarse distribution was known by CO observations. In this presentation, we report a detection of heavily obscured infrared source located toward the interaction region. The source is bright in infrared >24 um and Subaru PAH 3.3 um band images. If the supernova remnant and the source are really associated system, the formation of the infrared source could be induced by the impact of the supernova progenitor.
