Flow rate detection device and method for manufacturing the same

摘要

A flow rate detection device has a flow rate detection chip that is partially exposed to the flowing material to be measured and a casing that accommodates the flow rate detection chip. The casing has a bottom plate portion on which the flow rate detection chip is mounted, and a top plate portion that is disposed over the bottom plate portion and partially covers the flow rate detection chip. The space between the bottom plate portion and the top plate portion is filled with a sealant.
