## Abstract

An infrared light source device includes: a heater portion which emits infrared light by being heated; and a cover member arranged to cover an entire circumference of the heater portion without contacting the heater portion, and having a hole formed therein for emitting the infrared light from the heater portion to outside. A material for the cover member is a pure aluminum (an aluminum alloy with a purity of 99% or more), which has a high heat reflectivity and is less likely to be denatured by heat dissipation from the heater portion.

## Claims

### Claim 1

An infrared light source device comprising:
a heater which emits infrared light by being heated; and
a cover member arranged to cover an entire circumference of the heater without contacting the heater, and having a hole formed therein for emitting the infrared light from the heater to outside, wherein a material for the cover member is aluminum with a purity of 99% or more;
a material for an inner wall of the cover member being aluminum or gold.

### Claim 2 (depends on 1)

The infrared light source device according to claim 1, further comprising
a support member into which the heater and the cover member are fitted, wherein
in a state where the heater and the cover member are fitted into the support member, the cover member is arranged to cover the entire circumference of the heater without contacting the heater.

### Claim 3 (depends on 1)

A Fourier transform infrared spectroscope comprising the infrared light source device according to claim 1.
