<p>PROBLEM TO BE SOLVED: To solve such problems of a case for housing a high frequency circuit that since a radio wave absorber is provided on a cover in order to prevent internal resonance, and unnecessary radiation of radio waves to the outside, an expensive metal film capable of soldering or brazing the cover to the radio wave absorber is required, and that the radio wave absorber is susceptible to cracking due to the difference of linear expansion between the cover and the radio wave absorber, because of strong bonding by solder or brazing material.SOLUTION: A radio wave absorber is secured to a cover by means of a metal band that is bonded to the cover by solid phase bonding or welding.</p> |
