PROBLEM TO BE SOLVED: To provide a consumer electronic apparatus package which uses a metal substrate and is effectively available as a housing for many kinds of products.SOLUTION: The consumer electronic apparatus package comprises: a metal substrate 14 forming a housing; a plurality of electrically insulated contacts extending through the metal substrate 14; an electric insulation sleeve formed on a via sidewall 34; and a conductive filler 50 held by the insulation sleeve of the via sidewall 34. Each of the plurality of electrically insulated contacts includes: a first opening 40 of a top face in a part of the housing; a second opening 44 of a bottom face which is an opposite side of the part of the housing; and a penetration via 30 including the via sidewall 34 extending from the first opening 40 to the second opening 44. The electrically insulated contacts form a pattern on an outside surface of the housing, and an electric signal passes to the inside of the consumer electronic apparatus package via the conductive filler 50 of the consumer electronic apparatus package.
