To provide a resin for an eaves gutter base material and a manufacturing method of eaves gutter using this resin capable of continuously manufacturing the eaves gutters of which outside surfaces are coated with weatherproof resins having mutually different color tones under the same manufacturing condition by using the same shaping metal mold.

In this eaves gutter, thermoplastic resins for a body base material and for body outside surface coating are laminated in two layers. The resin for the base material is a vinyl chloride resin mixed with at least a pigment and an inorganic filler. The inorganic filler is wollasnite, and is blended by 10 pts.wt. to 50 pts.wt. to 100 pts.wt. of the vinyl chloride resin. The pigment is a noncarbon pigment, and is blended with 0.1 pts.wt. to 3 pts.wt. to 100 pts.wt. of the vinyl chloride resin.
