<P>PROBLEM TO BE SOLVED: To provide an electronic control unit which can prevent void generation and excels in waterproof performance. <P>SOLUTION: While a connection box 31 is fitted with a connector 32 and while a housing chamber 35 for the connection box 31 has its reference plane BP held horizontally, a fluid resin 380 is poured into the housing chamber 35. The liquid level of the fluid resin 380 rises inside a cylindrical portion 47 of a connector housing 41 from a first end part 53 of the cylindrical portion 47 to a second end part 54 at higher elevation. To ensure that the fluid resin inside the cylindrical portion 47 has no dead air space remaining therein, an inside upper wall 58 of the second end part 54 is inclined so as to be displaced upward as it goes toward a second opening 57 of the second end part 54. <P>COPYRIGHT: (C)2013,JPO&INPIT |
