Claims

[Scope of utility model registration request]

A support for a laminated thin film filter having a central annular part having a central through hole, a filtration part having a mesh opening in contact with the outer periphery of the central annular part, and an outer annular part in contact with the outer periphery,
A plurality of upper and lower through holes are provided in the central annular portion that penetrate through the upper and lower surfaces, and a plurality of grooves are provided in the upper surface that communicate the upper and lower through holes with the mesh opening.
In addition to providing a plurality of grooves radially on the lower surface that communicate the upper and lower through holes and the central through hole, the filtration section is divided into an upper layer, a middle layer, and a lower layer, and the upper layer and the lower layer have mesh-like openings arranged in a repeating cycle. The opening length is larger than that in the skeleton at least in the radial direction, and the mesh-like openings in the upper layer and the lower layer are arranged in phase with each other by 4- of the repetition period in the radial direction. 1. A support for a laminated thin film filter, which is set staggered, has a hollow middle layer, and is provided with struts for connecting the upper and lower layer skeletons at a portion where the vertical projections of the upper and lower layer skeletons overlap.
