Conventional heater units have a problem in that both ventilation characteristics and mechanical strength cannot be satisfied at the same time. A heater unit includes a base material (11) and a cord-shaped heater (10), the cord-shaped heater (10) being disposed on and fixed to the base material (11), in which the base material (11) is made by combining a structural yarn (11a) that is disposed in an approximately planar shape and a nonwoven fabric (11b) with each other, and the cord-shaped heater (10) is fixed in direct contact with the structural yarn (11a).

The present invention provides a zirconia sintered body that excels in both mechanical strength and translucency, and a zirconia molded body and zirconia pre-sintered body capable of providing such a zirconia sintered body, and containing a binder in an amount that assumes a thickness of 10 mm or more. The invention also provides methods of production of these. The present invention relates to a zirconia molded body comprising: a zirconia particle containing 2.0 to 9.0 mol% of yttria relative to the total number of moles of zirconium oxide and yttria, and having an average primary particle diameter of 60 nm or less; a polyol; and a binder, the polyol and the binder satisfying the relational formula X1 < Y1 < X2 < Y2 <_ 500°C.
