A heater according to embodiments includes: a base portion which contains metal, extends in a first direction, and has a first surface and a second surface facing the first surface; an insulating layer which is provided on the first surface side of the base portion; a heating element which is provided on the insulating layer and extends in the first direction; and a protection portion which covers the heating element. A peripheral edge of the base portion in a second direction intersecting the first direction extends in a third direction intersecting the first direction and the second direction.

Heater and image forming apparatus

Provided is a heater including: a substrate that has electrical conductivity; a first insulation portion that is provided on a first surface of the substrate, has an insulation property; at least one heat generation body that is provided on the first insulation portion; a second insulation portion that is provided on a second surface of the substrate which is opposite to the first surface, has an insulation property; at least one detection unit that is provided on at least one of the first insulation portion and the second insulation portion; and a first wiring which is provided on at least one of the first insulation portion and the second insulation portion, and in which one end is electrically connected to one terminal of the detection unit and the other end is electrically connected to the substrate having the electrical conductivity.

There is provided a discharge lamp of an embodiment includes a burner having a light emitting part, and a disk-shaped flange which is capable of holding the burner so that the light emitting part is positioned at a front end side of the flange. The flange includes a resin part formed at an edge of the flange, and a metal part formed to be embedded in the resin part.

Discharge lamp and discharge lamp apparatus

A mercury-free vehicle discharge lamp is described as including a discharge space with electrodes, wherein a spherical length b, which is a length in a tube axial direction of the light emitting part is 7.5 mm to 8.5 mm and a thickness volume V of the light emitting part is 50 mmto 100 mm, and wherein the following formula is satisfied: &#x2212;20&#x2266;(a&#x2212;35)&#xd7;5.5+(x&#x2212;13.5)&#xd7;10 +(1.85&#x2212;t)&#xd7;100+(2.5&#x2212;d)&#xd7;100&#x2266;20, a: power W supplied in a stable lighting time, x: pressure [atm] of rare gas sealed in the discharge space ranging 10&#x2dc;17 atm, t: thickness [mm] of a part where a wall with maximum thickness and ranging 1.30&#x2dc;1.85 mm, and d: inner diameter [mm] of a part where the wall with maximum thickness.
