A Magneto-Optical Trap (MOT) for <TEX>$^{87}Rb$</TEX> atoms near the surface of a dielectric coated mirror at the top of a small <TEX>$20{\times}25{\times}40\;mm^3$</TEX> cell has been observed. Two beams of <TEX>$3.3\;mW/cm^2$</TEX> were used for optical cooling and an anti-Helmholtz magnetic field with a spatial gradient of 9.1 G/cm was used for magnetic trapping. The thickness of the mirror coated on a cover glass was less than <TEX>$100{\mu}m$</TEX>. The mirror covered the top of a cell and the atom-chip was located outside the vacuum in order to exploit the long life time of the mirror and easy operation of the chip. The trapping position was found 5 mm beneath the mirror surface. The number of trapped atoms was roughly <TEX>$3{\times}10^7$</TEX> atoms and the temperature was approximately a few tens mK. In this paper, we describe the construction of the mirror-MOT in detail.
