We formulate the relation between the beam pattern and the source confusion limit. In the formula for the general number counts, the upper cutoff of the integration is set to obtain a numerically reasonable result. The upper cutoff corresponds to the beam area, so we input the beam pattern as the two-dimensional array of the Point Spread Function (PSF). Based on the representative number counts, we evaluate the source confusion typical of various infrared spacecrafts (e.g. ASTRO-F).
