PURPOSE: An underground line box is provided to minimize causes of trouble such as corrosion and short circuit of electric wires by preventing permeation of garbage to a connection tube. CONSTITUTION: An underground line box includes a main body, an anti-droop unit, and a cover unit. The main body includes a storage unit(24), a plurality of connection holes(26a,26b,26c), a projection(27), and a space part(28). The storage unit is used for storing electric wires(60). A plurality of connection tubes are inserted into the connection holes. The projection is formed at a bottom side of the connection holes. The space part is formed at a bottom side of the projection. The anti-droop unit(30) prevents a drooping phenomenon of the electric wires. The cover unit(40) is loaded on a top part of the main body. A handle(42) is formed at a center of the cover unit.
