PROBLEM TO BE SOLVED: To provide an -caprolactam polymer molded product in whose whole body a filler is homogeneously dispersed, and to provide a method for producing the molded product. SOLUTION: This method for producing an -caprolactam polymer molded product containing a filler comprises a process for heating a mixture of - caprolactam polymer with -caprolactam at a temperature above the melting point of the -caprolactam to obtain the homogeneous solution of both the components, a process for adding the filler to the homogeneous solution or preliminarily adding the filler to the mixture, and a process for injecting the obtained homogeneously filler-dispersed mixture into a mold and then leaving the injected mixture under conditions for polymerizing the -caprolactam.
