A technology for producing biocoke from biomass as a raw material, especially a process for producing biocoke that realizes efficient production of biocoke usable as a substitute fuel for coal coke and a product thereof. The process includes the divided charging step of carrying out divided charging of a biomass pulverizate (10) into a reaction vessel (1) multiple times and the preliminary pressurization step of at every divided charging, carrying out preliminary pressurization of the dividedly charged matter with a partition thin layer (4) disposed on the surface of the dividedly charged matter under a pressure not higher than given pressure range. Pressure molding of the laminate composed of multiple dividedly charged matters and partition thin layers (4) alternately superimposed one upon another by repetition of the divided charging step and preliminary pressurization step is carried out while maintaining the pressure range and temperature range for inducing a pyrolytic or thermal curing reaction of hemicellulose thereof without complete carbonization.
