PROBLEM TO BE SOLVED: To provide a method for producing an extrusion molding which allows an early detection of mixing ratio fluctuation of resin pellets to be measured and mixed when producing the extrusion molding using two or more thermoplastic resin pellets and also to provide a production machine for extrusion molding therefor. SOLUTION: The method for producing the extrusion molding which detects the mixing ratio fluctuation of the resin pellets by monitoring an operation interval of a measuring and mixing machine. On producing the extrusion molding, two or more resin pellets are intermittently mixed in a fixed amount by the measuring and mixing machine and discharged to a silo followed by feeding into a fusion extruder at the subsequent stage of the silo for producing the molding and, the fixed amount mixing is performed each time when a quantity of the resin pellets in the silo hits a preset lower limit.
