PROBLEM TO BE SOLVED: To provide an electronic circuit device improving reliability by preventing a corrosion of metal wirings of an electronic circuit chip and adapted to a recent year environmental problem. SOLUTION: The electronic circuit device comprises a first board 10 having first wiring parts (11a, 12a), an electronic circuit chip 4 connected to the part 11a and mounted on the board 10, an insulating resin layer 7 formed on the board 10 and the chip 4, and a second board 20 having wiring parts (24a, 21a) formed on the layer 7. In this case, the layer 7 is constituted of a material to become a content of a halogen or the like capable of suppressing a corrosion of the wiring of the chip 4 to be contacted with.
