A frame-shaped peripheral wall member is disposed on a holder so as to surround an electrical connection portion between a terminal and a flow rate detecting element, a bottom surface of the peripheral wall member being secured by bonding to the holder and the flow rate detecting element by a heat-curing addition-reaction silicone adhesive. A heat-curing addition-reaction gel containing a fluorine resin as a major constituent is injected and cured inside the peripheral wall member so as to embed the electrical connection portion.
