A turbine includes: a rotatable impeller with a hub provided with a plurality of rotor blades; and a tubular member in which a diffuser located downstream of the impeller is formed. On an inner surface of the tubular member, a plurality of projections projecting radially inward of the tubular member are formed at positions closer to an inlet end of the tubular member than an outlet end of the tubular member. The plurality of projections are arranged in a circumferential direction of the inner surface so as to leave a space between adjacent projections.
