<P>PROBLEM TO BE SOLVED: To solve the problem in which an infrared absorption film is required to have good infrared absorption efficiency and also required to be easily manufactured in terms of materials and manufacturing facilities. <P>SOLUTION: An infrared absorption film 9 is formed on a ground layer 8 and includes copper (Cu) as a main component. The surface shape of the infrared absorption film is a leaf shape 9A and is also oxidized. Therefore, since the infrared absorption film includes Cu as a main component and requires no special manufacturing facilities, the infrared absorption film can be easily manufactured to enable forming of the infrared absorption film with good infrared absorption efficiency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
