To provide a heater device which prevents air from stagnating inside even when a heater body where a heating medium flows is attached obliquely.
The heater device has a travel path having a tilt angle θ to a horizontal plane to dry a long base material 1 traveling along the travel path. In the heater device, a plurality of heater parts 42 are arranged along the travel path. The heater includes: a cylindrical heater body 42 having a flat lower surface and a semi-circular cross section; a radiation surface 44 provided on the lower surface of the heater body 42 and emitting far-infrared rays; an inflow hole 48 opened on one end surface 46 of the heater body 42; and an outflow hole 50 opened on the other end surface 52 along the travel path; The inflow hole 48 and outflow hole 50 are provided at the positions rotated upward at θ° with respect to a normal extended from the center of the under surface.
