Abstract
A heater includes a first ceramic substrate having a heating face on one main face thereof; a second ceramic substrate disposed so that one main face thereof covers the other main face of the first ceramic substrate; a heat generating resistor disposed on the one main face of the second ceramic substrate; and an adhesive layer which bonds the first ceramic substrate and the second ceramic substrate while covering the heat generating resistor.
Claims3
A heater, comprising:
- a first ceramic substrate having a heating face on a first main face thereof;
- a second ceramic substrate disposed so that a first main face of the second ceramic substrate covers a second main face of the first ceramic substrate;
- a heat generating resistor disposed on the first main face of the second ceramic substrate;
- and
- an adhesive layer which bonds the first ceramic substrate and the second ceramic substrate while covering the heat generating resistor
- wherein the first main face of the second ceramic substrate includes a groove section, and the heat generating resistor is disposed on a bottom face of the groove section along a profile of the groove section,
- wherein a thickness of the heat generating resistor is smaller than a depth of the groove section,
- wherein the thickness of the heat generating resistor becomes gradually smaller toward a center side in a width direction of the groove section, and
- wherein the second ceramic substrate is 1 to 10 mm in thickness.
