The present invention relates to a manhole comprising: a square plate-shaped lower member (20) for forming the bottom surface thereof; and an upper member (30) for connecting both sides of the lower member (20) in an arch shape so as form a space (35), in which a cable can be located, between the upper member (30) and the lower member (20).
