We present mid-infrared spectroscopy of the hyperluminous infrared galaxy IRAS 09104+4109 based on observations with ISOCAM CVF. We have detected the emission peak around 8 μm as well as the absorption feature around 10 μm possibly due to silicate, providing evidence for a dusty torus around the central engine. Comparing the observational results with the dusty torus model studied by Pier & Krolik (1992), we show that the most mid infrared emission comes from a compact (a few pc in radius) dusty torus although the excess far infrared emission suggests the presence of an extended dusty torus with radius of ∼ 100 pc.
