PROBLEM TO BE SOLVED: To provide an electronic circuit board to which electronic components with different terminal pitches can be commonly mounted compactly in an optimum manner while reducing unnecessary space at most. SOLUTION: The electronic circuit board 1 is provided with: the first mount parts 28 including a plurality of through holes 21, 22, 23 disposed in parallel corresponding to each lead terminal of a large scale diode; and the second mount parts 29 including a plurality of through holes 24, 25, 26 disposed in parallel corresponding to each terminal of a small scale diode. A plurality of first mount parts 28 are disposed, each being spaced apart from one another, to mount a plurality of large scale diodes. The second mount parts 29 are disposed between one neighboring first mount part 28 and the other neighboring first mount part 28, and the through hole 24 positioned at one end of the second mount part 29 is also available as the through hole 23 at the other end of the first mount part 28. The through hole 26 positioned at the other end of the second mount part 29 is also available as the through hole 21 at the other first mount part 28. COPYRIGHT: (C)2009,JPO&INPIT
