Claim of US Patent No. 10,143,042

1. A heating device comprising:a heater; and
a support member that supports the heater and comprises bio-soluble inorganic fibers,
wherein the bio-soluble inorganic fibers are Mg silicate fibers having the following composition or Ca silicate fibers having the following composition:
[Mg silicate fibers]
SiO2: 66 to 82 wt %
CaO: 1 to 9 wt %
MgO: 10 to 30 wt %
Al2O3: 3 wt % or less
Other oxides: less than 2 wt %
[Ca silicate fibers]
SiO2: 66 to 82 wt %
CaO: 10 to 34 wt %
MgO: 3 wt % or less
Al2O3: 5 wt % or less
Other oxides: less than 2 wt %
wherein the heating device comprises any coating of the following configurations (1) to (3); and due to the coating, the bio-soluble inorganic fibers do not contact directly the heater or the contact of the bio-soluble inorganic fibers with the heater is reduced compared with a heater without the coating:(1) at least surfaces of the support member that contact the heater are coated;(2) bio-soluble inorganic fibers that are present on at least surfaces of the support member that contact the heater are coated; and(3) the heater is coated.
