PROBLEM TO BE SOLVED: To provide a technique capable of manufacturing half-split chopsticks made of a resin at a low cost. SOLUTION: A manufacturing apparatus for the half-split chopsticks made of the resin comprises an extruding means 1 for extruding rod-like bodies made of the resin, rotating rollers 5a and 5b provided by opposing each other, recessed channels 6a and 6b formed on the peripheral sides of the rotating rollers, partitioning walls 7a and 7b having shapes corresponding to split channel parts formed on the half-split chopsticks, with shorter lengths than the whole lengths of the half-split chopsticks and provided in the recessed channels. The manufacturing apparatus is constituted so that two pieces of the rod-like bodies made of the resin extruded by the extruding means are guided into one recessed channel on the peripheral sides of the rotating rollers, and during passing through the recessed channels, the rod-like bodies made of the resin are joined only on a part where no partitioning wall exists.
