There is a need for providing a flow sensor with metal film resistor that improves detection sensitivity using a metal film for a resistance heat detector and a resistance temperature detector. The flow sensor with metal film resistor is structured to form a resistance heat detector, a resistance temperature detector for resistance heat detector for measuring temperature of the resistance heat detector, an upstream resistance temperature detector, a downstream resistance temperature detector, and an air resistance temperature detector on a silicon substrate. Plural floating-island insulators are provided for the resistance heat detector and within wiring thereof.
