The present invention provides a Natural gas fuel evaporator, natural gas fuel supply device, and method for supplying natural gas fuel to ships and motors. The purpose of the present invention is to reduce the cost of fuel gasification equipment for LNG and other liquefied gas. The methane component of LNG liquid inside a holding tank (21) is evaporated, turned into LNG gas, and discharged from the holding tank (21), by: supplying LNG liquid that has been heated by a heating unit (22), putting LNG liquid inside the holding tank (21) into a saturated state, opening a throttle valve (33); and reducing the pressure inside the holding tank (21). In addition, it is preferable that the accumulation of heavy components inside the holding tank is avoided by supplying some of the LNG liquid inside the holding tank (21) to a desuperheater (43), via a branch pipe (50).
