description PURPOSE:To easily judge whether an electronic component has been detached by a method wherein a colored part with a size which is hidden by the electronic component to be mounted is formed on a printed-circuit board in s position where the electronic component is mounted on the printed circuit board. CONSTITUTION:An electronic component 2 is mounted on conductors 3. A colored part 4 with a size which is hidden by the component 2 is formed on the printed circuit board. In a normal state, the colored part 4 cannot be observed visually; while in an abnormal state, the colored part 4 can be observed visually; accordingly, it is judged whether the component 2 has been detached.
