This weld metal has excellent creep characteristics and has a given chemical composition. In the weld metal, the value A defined by equation (1) is 200 or greater, and carbide particles each having an equivalent-circle diameter of 0.40 μm or more have an average equivalent-circle diameter less than 0.85 μm. In the segments that connect the centers of three or more carbide particles which are present on a 6-μm straight line and which each has an equivalent-circle diameter of 0.40 μm or more, the sum of the lengths of the portions where the segments intersect the carbide particles is 25% or more of the overall length of the segments. Value A=([V]/51+[Nb]/93)/{[V]×([Cr]/5+[Mo]/2)}×104  (1) In the equation, [V], [Nb], [Cr], and [Mo] respectively indicate the contents (mass %) of V, Nb, Cr, and Mo in the weld metal.
