Abstract: In a copper-based slide member in which needle-shaped Mn—Si based compounds are dispersed in a brass structure, 50% or more of a total number of the needle-shaped Mn—Si based compounds having lengths of 50 μm or more in a major axis direction are constituted of a plurality of small particles. Thereby, even if the needle-shaped Mn—Si based compounds fall off during sliding, the small particles which constitute the needle-shaped Mn—Si based compounds may fall off. Thus, the frequency of falling off of the coarse needle-shaped Mn—Si based compound which damages a shaft and a bearing is decreased. Therefore, seizure hardly occurs.
