PROBLEM TO BE SOLVED: To obtain a substrate box which efficiently radiates heat from a substrate housed in a case while having good assemblability.SOLUTION: In a power source box 1A, substrates 6A, 6B, on which electronic components are provided, are housed in a case 2. The power source box 1A has: attachment units 10A, 10B which have placement surfaces 11a where the substrates 6A, 6B are placed and are housed in the case 2; and extending means 20A extending in the case 2 and placing rear surfaces of the placement surfaces 11a of the attachment units 10A, 10B in close contact with the case 2. |
