    • In order to provide a thermal flow meter capable of preventing adherence of contaminants to an air flow sensing portion, the thermal flow meter (300) of the invention includes a bypass passage for flowing a measurement target gas (30) received from a main passage (124) and an air flow sensing portion (602) for measuring a flow rate of the measurement target gas (30) by performing heat transfer with the measurement target gas (30) flowing through the bypass passage through a heat transfer surface (437). The air flow sensing portion (602) is provided to be exposed to an exposed surface (402) arranged along a flow direction of the measurement target gas (30) inside the bypass passage is embedded, the mount support surface (402) has a stage (407) formed to surround a periphery of the air flow sensing portion (602), and an inner portion surrounded by the stage protrudes more than an outer portion of the stage.
    • 为了提供能够防止污染物与气流感测部的粘附的热流量计,本发明的热流量计(300)包括用于使从主通路(1)接收的测量对象气体(30)流动的旁通通路 124)和用于通过使流过旁通通路的测量对象气体(30)通过传热面(437)进行传热来测量测量对象气体(30)的流量的气流感测部(602)。 空气流动检测部分602被设置为暴露于沿旁路通道内部的测量对象气体30的流动方向布置的暴露表面402,安装支撑表面402具有一个阶段 (407),其形成为围绕所述气流检测部(602)的周边,并且由所述台围绕的内部部分比所述台的外部突出。
