PROBLEM TO BE SOLVED: To provide a mechanical sealing device, having excellent durability and dry sliding resistance, preventing seizure and abrasion of a sealing slide member, and effectively restraining the generation of squeak in sliding. SOLUTION: This mechanical sealing device butts and seals a first sealing slide member and a second sealing slide member to each other. The first sealing slide member is a sealing slide member taking silicon carbide as base material, and containing carbon. The second sealing slide member is a sealing slide member containing silicon carbide as the main component, in which pores having a pore diameter ranging from 5 to 200μm are dispersed independently.
