Claims

[Scope of utility model registration request]

In a case comprising a chassis, a cover that closes the upper and lower surfaces of the chassis, and at least one shield plate inside the chassis, and a space divided into a plurality of parts for storing a high frequency circuit, the chassis and the shield plate are provided. It is formed into a box-bent shape from a single plate, and in order to prevent the leakage gap of high frequency components that occurs between the chassis, the end face of the shield plate, and the cover, a protrusion is provided from the chassis or cover surface to fill the gap. A housing structure for high-frequency equipment that is characterized by a high degree of airtightness.
