PROBLEM TO BE SOLVED: To provide a down-sized structure for fixing a substrate and a unit of heat source equipment which can be down-sized by attaching a substrate with such a structure for fixing a substrate.SOLUTION: In a structure for fixing a substrate, a substrate 40 is attached to a fixing object 42 via a substrate case 58 which can house the substrate 40 and a box 59 for attachment which can house the substrate case 58. The box 59 for attachment is in a state where at least one side is opened to have its inside communicating with outside, and the substrate case 58 is inserted from the opened side to house the substrate case 58 inside. Also, the substrate case 58 is housed inside the box 59 for attachment, thereby the movement of the substrate case 58 in directions other than an ejection direction is restricted and external movement restriction means 50 restricts the movement of the substrate case 58 in an ejection direction when the box 59 for attachment is attached to the fixing object 42. |
