A two-fluid dispenser capable of reducing odor, even when one of two fluids dispensed in foam has pungent odor. The dispenser includes: a first and a second dispenser container each including an upper surface from which a stem protrudes and is configured to dispense a fluid therein in foam in response to the stem depressed; and a dispenser tool fixedly fitted over the containers. The dispenser tool includes a dispenser head communicating with the containers and including a nozzle, so that when the dispenser head is depressed, the fluids are dispensed from the containers through the nozzle. The dispenser head includes a fluid guide mechanism to guide the fluids from the containers to be dispensed in foam through the nozzle such that the fluids have a layered pattern in which a first fluid layer is at least partly covered by a second fluid layer.
