摘要：
A vitrified grinding stone includes: abrasive grains; an inorganic binder that binds the abrasive grains; and air-communicating pores that are formed between the abrasive grains and the inorganic binder, micro-capsules that each encapsulate a lubricant and each have a diameter that is smaller than that of the air-communicating pore, being fixed on an inner wall surface of each of the air-communicating pores by an adhesive.
