PROBLEM TO BE SOLVED: To make a pouring device for molten metal compact. SOLUTION: A pump for sucking/delivering the molten metal with a piston 2 in a cylinder 1, a molten metal pouring pipe line 5 for pouring the molten metal D in the cylinder into a mold, and a spool type valve element 8 slidably shifted in the vertical direction to the pouring position communicating the cylinder with the molten metal pouring pipe line and to the sucking position disconnecting them, are arranged and the molten metal pouring pipe line is constituted of an upstream side pipe line 41 parallel with the shifting direction of the valve element and a down stream side pipe line 42 in the direction crossing the above direction. The upstream side pipe line and a valve seat 46 are arranged in series and the valve element and a valve stem 42 are connected in series, and the valve stem is made to pass through the upstream side pipe line and the operating side end part of the stem is projected through a through- hole 48 of a pipe line forming member 43 and a heater 52 is arranged in the inner part of the valve stem made to pass through the upstream side pipe line.
