<P>PROBLEM TO BE SOLVED: To provide a heating element unit that can reduce an electric resistance and can improve heating responsiveness, and to provide an evaporated fuel treatment device. <P>SOLUTION: The heating element unit 71 includes a PTC heater 73 which generates heat by being carried with electricity, and a honeycomb core 44 which has air permeability and radiates heat generated at the PTC heater 73. The honeycomb core 44 is constituted by laminating a plurality of metal foil materials 45, and developing, in a lamination direction, a laminate 50 which is joined so that the adjacent metal foil materials 45 are parallel with each other at each prescribed pitch, and a joining portion is arranged zigzag in the lamination direction. The PTC heater 73 is a sheet-shaped heating element which has plasticity and is arranged between the adjacent metal foil materials 45 of the honeycomb core 44. <P>COPYRIGHT: (C)2012,JPO&INPIT |
