To provide a heater unit in which breaking of wire of a heater element can be prevented, and a vehicular seat using the heater unit.SOLUTION: In a heater unit comprising a base material 11 and a heater element arranged on the base material, a plurality of warming portions are coupled with each other by a coupling portion having width narrower than that of the warming portion, and a protective member 11b made of an elastomer material is arranged in the coupling portion. The hardness of the protective member 11b is A60 or more and A80 or less. A vehicular seat comprises: a seat skin 43 and a seat pad 45. A suspension portion 47 for fixing the seat skin 43 to the seat pad 45 is formed in the vehicular seat. The heater unit is arranged between the seat skin 43 and the seat pad 45. The warming portions are arranged in such a manner that the warming portions avoid a spot where the suspension portion 47 is located. The coupling portion is arranged at a spot where the suspension portion 47 is located.SELECTED DRAWING: Figure 9
