PROBLEM TO BE SOLVED: To obtain the subject molded product largely improved in handleability and sufficient in dispersibility in vehicles by press-molding carbon black. SOLUTION: This carbon black molded product is produced by press-molding carbon black. The obtained molded product preferably has a densityρ(g/cc) of 8.190×10<-3> D-3.824×10<-3> L+0.516 to 3.265×10<-3> D-3.334×10<-3> L+1.173, wherein D(mm) is an arithmetical average particle diameter of the carbon black by the use of an electronic microscope, and L(mL/100g) is a DBP oil absorption. The carbon black molded product has cut lines, which can be formed e.g. by carving the molded product with a cutter blade or grooving the molded product with a drill.
