We investigated on the three-level ladder-type electromagnetically-induced transparency (EIT) of the 5S$_{1/2}$-5P$_{3/2}$-4D$_{5/2}$ transition in a $^{87}$Rb atomic ensemble by using a magneto-optical trap (MOT). The cold atoms had a cigar-type shape due to two-dimensional MOT. When a weak probe field with a wavelength of 780 nm and a strong coupling field with a wavelength of the 1529 nm interacted with the cold $^{87}$Rb atoms, a Doppler-free ladder-type EIT signal could be observed in the 5S$_{1/2}$(F=2)- 5P$_{3/2}$(F$^\prime$=3) - 4D$_{5/2}$(F$^{\prime\prime}$=4) transition by irradiating the cold atomic ensemble with the coupling and the probe lasers.
