Summary:PROBLEM TO BE SOLVED: To provide a thermal type flowmeter capable of mitigating a stress applied to a lead terminal, even when being used under an environment to which a hot-cold cycle is applied.SOLUTION: In a direction in which a first straight line part 41 and a second straight line part 42 are orthogonal mutually, when expressing a distance from a center line Ln between the first straight line part 41 and the second straight line part 42 to the most separated position of the center line of a third bent part 45 as a crest height H of the bent part, and expressing a terminal thickness of a lead terminal 412 as T, a relation 4≤H/T≤10 is satisfied.SELECTED DRAWING: Figure 7B 【課題】冷熱サイクルが作用する環境下で使用する場合であっても、リード端子に作用する応力を緩和することができる熱式流量計を提供することにある。【解決手段】第１直線部４１と第２直線部４２とが直交する方向において、第１直線部４１および前記第２直線部４２の中心線Ｌｎから第３屈曲部４５の中心線の最も離れた位置までの距離を屈曲部の山高さＨとし、リード端子４１２の端子厚さをＴとしたときに、４≦Ｈ／Ｔ≦１０の関係を満たす。【選択図】図７Ｂ
