PROBLEM TO BE SOLVED: To provide a double sided substrate which can increase a degree of freedom for a layout while maintaining insulation quality and waterproofness. SOLUTION: A double sided substrate has a substrate body 2 which electronic components 100 and 104 are respectively placed on front and rear surfaces. A first electrode 6a electrically connected with the electronic component is provided on the front surface side of the substrate body 2, and a second electrode 6b electrically connected with the electronic component is provided on the rear surface side of the substrate body 2. The substrate body 2 is covered by a package 3 made of a resin mold as well as the electronic components. The first electrode 6a and the second electrode 6b respectively have contact surfaces which are exposed on a surface of the package 3 for being electrically connected with external terminals, and the contact surfaces are respectively recessed from the surface of the package 3.
