PROBLEM TO BE SOLVED: To provide a sliding member with excellent durability in which excellent sliding characteristics such as small coefficient of friction and high wear resistance can be kept for a long time. SOLUTION: A sliding member is made of the sintered body which is <=5% in porosity, formed of at least 80%, by mass, titanium di-borate, and in which titanium di-borate in the sintered body is formed of particles of <=25μm in mean grain size. More specifically, the sliding member is formed of the sintered body of <=5% in porosity formed of 80-95% titanium di-borate, 2.5-17.5% chromium borate, and 2.5-17.5% titanium carbonate, and titanium di-borate in the sintered body is formed of particles of <=25μm in mean grain size.
