  We present high spatial resolution images of the gravitational-lens system PG
1115+080 taken with the near-infrared camera (CISCO) on the Subaru telescope.
The FWHM of the combined image is $0.''32$ in the $K'$-band, yielding spatial
resolution of $0.''14$ after a deconvolution procedure. This is a first
detection of an extended emission adjacent to the A1/A2 components, indicating
the presence of a fairly bright emission region with a characteristic angular
radius of $\sim$ 5 mas (40 pc). The near-infrared image of the Einstein ring
was extracted in both the $J$ and $K'$ bands. The $J-K'$ color is found to be
significantly redder than that of a synthetic model galaxy with an age of 3
Gyr, the age of the universe at the quasar redshift.
