Claim:
1. A sensor of a thermal flow measuring device, comprising: a sensor platform, which bears at least one measuring sensor element and a heated sensor element, each of said sensor elements is surrounded by a metal sleeve, which protrudes from said sensor platform; and a plate-shaped element, which defines a plane, whose axis extends parallel to the axis of at least one of said metal sleeves, said plane is spaced from said sensor platform in the axial direction of said metal sleeve, wherein said metal sleeve with said heated sensor element has a terminal end face; said plate-shaped element is provided along said terminal end face of said metal sleeve with said heated sensor element for flow guidance; at least 50% of a heating power required for said heated sensor element is given off as heat energy via said metal sleeve to a medium in a region, which is formed by said terminal end face; and a sleeve wall section, which starting from said terminal end face lies in the first third of said metal sleeve.
