Abstract
A reticulate heater for a steering wheel exhibits flexibility, elasticity and waterproofness. The reticulate heater comprises a reticulate heat generating element () consisting of a plurality of insulated heater wires () braided in a mesh form, and exhibiting flexibility and elasticity to permit tight contact with a curved surface, a waterproof stretch-film () covering the front and rear surfaces of the reticulate heat generating element () water-tightly and adhering to the reticulate heat generating element () while still keeping the flexibility and elasticity thereof, and an elastic adhesive () having flexibility and elasticity even after curing, applied to the whole surface of the stretch-film () on the adhering surface side in a planar and thin state, and bonding the stretch-film () to the reticulate heat generating element () water-tightly even if the stretch-film () is stretched within an allowable tensile range.
