PROBLEM TO BE SOLVED: To provide an electronic equipment which can closely arrange each electronic component by efficiently radiating heat generated in heating elements without increasing mounting parts to a substrate. SOLUTION: A power source device 1 includes a substrate 2 on which various kinds of electronic components such as a switching element 16, a coil L, and a capacitor C are mounted. Further, the each coil L is mounted on the heat transmission path of heat transmitted from the switching element 16 to the capacitor C, the respective coil L and the switching element 16 are connected to a conductive pattern 50 formed in the substrate 2. Moreover, the coil L is composed by a core material being pressed together into a block shape while the winding is encapsulated in the core material, the winding is covered with the core material.
