We observed an area of 10 $deg^2$ of the Large Magellanic Cloud using the Infrared Camera (IRC) onboard AKARI. The observations were carried out using five imaging filters (3, 7, 11, 15, and $24{mu}m$) and the prism disperser ($2-5{mu}m$, ${lambda}/{Delta}{lambda}{sim}20$) equipped in the IRC. This paper presents an outline of the survey project and also describes very briefly the newly compiled near- to mid-infrared point source catalog. The $10{sigma}$ limiting magnitudes are 17.9, 13.8, 12.4, 9.9, and 8.6 mag at 3.2, 7, 11, 15 and $24{mu}m$, respectively. The photometric accuracy is estimated to be about 0.1 mag at $3.2{mu}m$ and 0.06 - 0.07 mag in the other bands. The position accuracy is 0.3" at 3.2, 7 and $11{mu}m$ and 1.0" at 15 and $24{mu}m$. The sensitivities at 3.2, 7, and $24{mu}m$ are roughly comparable to those of the Spitzer SAGE LMC point source catalog, while the AKARI catalog provides the data at 11 and $15{mu}m$, covering the near- to mid-infrared spectral range continuously.
