PROBLEM TO BE SOLVED: To provide a printed substrate capable of effectively emitting heat to an external part, which is radiated from an electronic component, with a simple configuration. SOLUTION: The printed substrate 1 includes a plurality of through-holes 1a in a part with the electronic component 2 mounted thereon, so as to penetrate the printed substrate 1. The projected parts 3b of radiation components 3 are inserted to the through-holes 1a from the rear surface of the printed substrate 1. The distal ends of the projected parts 3b are brought into contact with the electronic component 2. The radiation components 3 are formed of a highly conductive metallic material. The heat radiated from the electronic component 2 is transmitted to the body part 3a on the rear surface of the printed substrate 1 via the projected parts 3b, and emitted from the body part 3a.
