PROBLEM TO BE SOLVED: To provide a sliding member, especially a piston ring, excellent in abrasion resistance, seize resistance, and peel resistance and having low aggressivity to a mate member. SOLUTION: The sliding member has a thermal spray coating film on at least a sliding face. The coating film mainly comprises hard particles A consisting of at least one kind of hard particles having an average particle size of 5-45μm and a composite powder B having chromium carbide particles with the average particle size of 5μm or less and dispersedly precipitated in a matrix consisting of a Ni-Cr alloy or consisting of a Ni-Cr alloy and Ni.
