When U-shape formed electronic components having an axial lead shape are mounted upright on a printed board, two U-shape formed electronic components having an axial lead shape are arranged so as not to be in the same straight line, and a wiring pattern is formed in a state where bent-side lead wires have the same electric potential, and the electronic components are inclined so as to place the bent-side lead wires close to each other, whereby the electronic components that tend to fall in the inclined direction can be mutually supported by the bent-side lead wires. Thus, the electronic components can be prevented from falling without spoiling a heat dissipation performance of the electronic component and the board, and without greatly deteriorating an assembly performance of the board. |
