PROBLEM TO BE SOLVED: To provide a method of manufacturing a high frequency device in which, even if a radio wave absorbent includes a ferrous oxide such as ferrite, the radio wave absorbent is joined to a lid body with high joint strength without application of a metal film or metallization and out gas is prevented from being generated even if heated at about 400°C in a seam-welding step of a post step.SOLUTION: There is disclosed a method of manufacturing a high frequency device in which, after a paste containing organic material-coated Ag particles having micro sizes and a solvent is printed on a lid body, and a radio wave absorbent having a surface roughness Ra of 0.5 μm to 10 μm is arranged on the printed paste so that the surface having the surface roughness and the paste come into contact with each other, tapping operation for applying impact to a direction to the lid body from the radio wave absorbent at a speed of 0.1 m/second to 1 m/second is performed three times or more. |
