PROBLEM TO BE SOLVED: To provide a heater unit excellent in air permeability and mechanical strength.SOLUTION: A heater unit comprises a base material 11 and a cord-like heater 10. The cord-like heater 10 is arranged on and fixed to the base material 11. The base material 11 is obtained by combining fiber threads 11a and nonwoven fabric 11c arranged in a substantially planar manner. The fiber threads 11a are woven or braided, or paralleled portions thereof in different directions are placed on top of each other. The heater unit has openings 11c each of which is larger than an apparent diameter of the fiber threads 11a. A vehicular seat comprises a seat skin and a seat pad, and has the heater unit arranged between the seat skin and the seat pad.SELECTED DRAWING: Figure 2
