PROBLEM TO BE SOLVED: To provide a multi-directional valve with excellent external seal performance and excellent flow characteristic, which prevents the looseness of a handle and regularly holds the valve opening constant. SOLUTION: This multi-directional valve comprises a PTFE-made valve body 1 comprising a main passage 9 provided in the lower part and a valve chamber 13 provided in the upper part and allowed to communicate with the main passage by a communicating port 12 provided vertically to the main passage 9, and the peripheral part of the opening part of the communicating port 12 is a valve seat 14. The valve chamber 13 is formed larger than the outer diameters of the opening part of the communicating port 12 and a valve element 24, and a pair of branch passages 10 and 11 communicating with the valve chamber 13 are provided on the upper side surface of the valve body 1 in the direction orthogonal to the main passage 9. The branch passages 10 and 11 are formed so that the position of the inside lowest part is substantially flushed with the bottom surface of the valve chamber 13.
