PROBLEM TO BE SOLVED: To allow the stable control of temperature by preventing foreign matter from adhering to a temperature sensing spring in a combination faucet for controlling the temperature of mixed water by using the temperature sensing spring of shape memory alloy. SOLUTION: In this combination faucet, a cartridge 9 installed in the storage chamber 4 of a body 1 comprises a hot water inlet 16 communicating with a hot water chamber 2 in the body 1, a water inlet 17 communicating with a water chamber 3, a control valve 24 for regulating the supplied amount of hot water from the hot water inlet 16 and the supplied amount of water from the water inlet 17 by axially sliding inside the cartridge 9, a temperature sensing spring 30 of shape memory alloy for energizing the control valve 24 from one side, and a bias spring 29 for energizing the control valve 24 from the other side. The energizing force of the bias spring 29 is adjusted by the operation of the temperature control handle 8 to control the temperature of the mixed water. A strainer 20 is installed at the hot water inlet 16 and the water inlet 17 of the cartridge.
