Abstract
A sensor for measuring the flow velocity of gases. The sensor includes a printed circuit board (1) having an opening (2) formed therein. A pair of first contact elements are disposed on opposing sides of the opening on an upper side of the circuit board (1), and a pair of second contact elements are disposed on opposing sides of the opening on a lower side of the circuit board (1). A first wire (4) with end portions respectively connected to the first contact elements extends across the opening (2) on the upper side of the circuit board (1). A second wire (10) with end portions respectively connected to the second contact elements extends across the opening (2) on the lower side of the circuit board (1).
