We report the observational findings of the Sh2-112 HII region by using the multiwavelength data analysis ranging from optical to radio wavelengths. This region is powered by the massive O8V-type star BD+45{deg}3216. The surface density distribution and minimum spanning tree analyses of the young stellar object (YSO) candidates in the region reveal their groupings toward the western periphery of the HII region. A GMRT radio continuum emission peak is found toward the northwest boundary of the HII region and is investigated as a compact/ultracompact HII region candidate powered by a B0-B0.5-type star. Toward the southwest direction, a prominent curved rim-like structure is found in the H{alpha} image and GMRT radio continuum maps, where the H_2_ and ^13^CO emission is also observed. These results suggest the existence of the ionized boundary layer (IBL) on the surface of the molecular cloud. This IBL is found to be overpressured with respect to the internal pressure of the surrounding molecular cloud. This implies that the shocks are propagating/propagated into the molecular cloud, and the young stars identified within it are likely triggered due to the massive star. It is also found that this region is ionization-bounded toward the west and density-bounded toward the east. Based on the distribution of the ionized gas, molecular material, and YSO candidates, we propose that the Sh2-112 HII region is a good candidate for the blister-type HII region that has been evolved on the surface of a cylindrical molecular cloud.
