INFRARED LAMP AND HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a small infrared lamp having a structure usable over a long time in a bulb having high infrared radiation intensity and directivity by improving a radiation distribution of the infrared lamp; and to provide a heating device using the infrared lamp. SOLUTION: This infrared lamp has one or more heating elements 2 each having a shape extending in the longitudinal direction, and a glass tube 1 wherein the heating element(s) 2 is(are) sealed and a part of a cross section vertical to the longitudinal direction is parabolic; and a reflecting film 7 is formed in the longitudinal direction in a part on the circumference of the glass tube 1 having the parabolic cross section.
