To provide a heater case capable of improving transfer efficiency of heat by bringing a heater and a housing into sufficient adhesion and proximity to each other without exerting adverse influences upon the heater, a heater device and an on-vehicle heater unit.SOLUTION: The present invention relates to a heater case in which a heater including a heating element is stored. The heater case comprises: a case main body including a passage in which a medium flows and having a contour of a rectangular column shape extending in a first direction; and a cylinder part provided along an outer surface of the case main body, extending in the first direction and including a space in which the heater is stored. The cylinder part includes: a sheath part provided substantially in parallel with an outer surface of the case main body while being spaced apart from the outer surface at a predetermined interval in a second direction orthogonal to the first direction; and a plurality of support parts, with a direction orthogonal to the first direction and the second direction as a third direction, provided between both ends of the sheath part and the outer surface in the third direction. Each of the plurality of support parts includes a narrowed portion extending in the first direction.SELECTED DRAWING: Figure 1
