PROBLEM TO BE SOLVED: To provide an electronic circuit board in which a conductive wire is not peeled off by temperature cycles in a use environment, and to provide a semiconductor device using the electronic circuit board.SOLUTION: An electronic circuit board comprises: a metal plate 1; an insulating layer 2 directly formed to the metal plate without an adhesive layer; and a conductive wire 3 formed to the insulating layer. The insulating layer has an inorganic insulation part 21 made of an inorganic material, and an inorganic/organic mixture insulation part 22 containing an organic material in cavities of the inorganic material. The inorganic/organic mixture insulation part is formed to at least a part of an interface between the insulating layer and the conductive wire. |
