Abstract: Disclosed is an electronic unit in which wiring patterns (2) and grounding patterns (3) provided on the upper surface (1a) of a circuit board (1) are connected to wiring terminal electrode portions (4) and grounding terminal electrode portions (5) by connection conductors (6) and (7), respectively, provided in through-holes, so that in mounting a cover (8), there is no need to avoid side through portions (21c) as in the prior art. Thus, it is possible for the cover to occupy the entire outer periphery of the upper surface of the circuit board (1), whereby it is possible to effectively utilize the entire upper surface la as a wiring pattern (2) and reduce the size of the electronic unit.
