There is provided a breather device for an engine which can prevent a blow-by gas outlet passage from being blocked due to freezing. A breather device for an engine includes: a valve holder 2 disposed in a cylinder head cover 1; and a breather valve 3 supported by the valve holder 2. The valve holder 2 includes: a holder body 5 having a valve port 4 of the breather valve 3; an outlet passage pipe 7 formed of metal and having a blow-by gas outlet passage 6 formed inside, the blow-by gas outlet passage 6 communicating with the valve port 4 and being located below the valve port 4; and a heater 8 that heats the outlet passage pipe 7. An outer peripheral surface of the outlet passage pipe 7 is wrapped with the holder body 5 formed of a material having lower thermal conductivity than that of the outlet passage pipe 7, the holder body 5 has a heater insertion port 9, and the heater 8 is inserted from the heater insertion port 9 toward a heat input wall 7a of the outlet passage pipe 7.
