A flow sensor is provided to avoid damage to the sensor arranged to face a flow path for detecting flow rate of a fluid flowing through the flow path. A flow sensor includes a main body(14) and a sensor(16). The main body has a flow path(12) formed by an upper wall(26) and a lower wall(28) at least. The sensor is disposed along the upper wall forming the flow path. The flow path includes a throttle surface(24a) and a first slope surface(24b) continuously formed at an upper side of the throttle surface. The first slope surface is disposed so that the flow path formed between the upper wall and the first slope surface is extended toward the upper side of the throttle surface. The first slope surface has an angle so that an extension line of the first slope surface passes an offset position toward the upper side of the throttle surface in comparison with a detecting part(16a) installed on a detecting surface(16b) of the sensor.
