To provide an electronic control unit which can improve the safety of a saddle-riding type vehicle.SOLUTION: An electronic control unit (5) according to the present invention comprises: an electronic circuit unit (52) which has a substrate (521) and a plurality of electronic components (522); and a housing (53) which stores the electronic circuit unit (52). A waterproof moisture-permeable member (535) that blocks a through hole (533) that makes the inside and the outside of the housing (53) communicate to each other is provided in the housing (53). In the normal time, the water circulation between the inside and the outside of the housing (53) is blocked by the waterproof moisture-permeable member (535), and gas can circulate through the waterproof moisture-permeable member (535). In the abnormal smoke generation time in which smoke is generated in the housing (53), clogging occurs in the waterproof moisture-permeable member (535) due to the smoke (S1) generated in the housing (53), and the circulation of the gas between the inside and the outside of the housing (53) is blocked by the waterproof moisture-permeable member (535).SELECTED DRAWING: Figure 4

    【課題】本発明は、鞍乗り型車両の安全性を向上させることができる電子制御ユニットを得るものである。【解決手段】本発明に係る電子制御ユニット(5)は、基板(521)と複数の電子部品(522)とを含む電子回路ユニット(52)と、電子回路ユニット(52)を収容する筐体(53)とを備え、筐体(53)には筐体(53)の内部と外部とを連通する貫通孔(533)を塞ぐ防水透湿性部材(535)が設けられており、通常時には、筐体(53)の内部と外部との間での水の流通が防水透湿性部材(535)によって遮断され、ガスが防水透湿性部材(535)を介して流通可能となり、筐体(53)内で発煙が生じている異常発煙時には、筐体(53)内で生じた煙(S1)によって防水透湿性部材(535)に目詰まりが生じ、筐体(53)の内部と外部との間でのガスの流通が防水透湿性部材(535)によって遮断される。【選択図】図4
