An on-vehicle electronic circuit mounting board includes: a surface mount type package component including a plurality of electrode pads disposed along an outer periphery of a component bottom surface; and a printed wiring board having a plurality of lands disposed along the plurality of electrode pads on a top surface of the printed wiring board opposed to the component bottom surface, and in which each land is disposed to be opposed to the corresponding electrode pad and electrically connected to the electrode pad by soldered connection. An outer soldering slope and an inner soldering slope are formed between a land of the plurality of lands and an electrode pad corresponding to the land, and the land is shifted with respect to the corresponding electrode pad such that one of the outer soldering slope and the inner soldering slope faces the wiring board side and the other faces the component side.
