Abstract:
1. A hybrid integrated circuit device comprising: a circuit board made of metal; a conductive pattern provided on a front surface of the circuit board; and a circuit element electrically connected to the conductive pattern, wherein a side surface of the circuit board includes a first inclined portion which extends obliquely downward from a peripheral portion of the front surface of the circuit board, and a second inclined portion which extends obliquely upward from a back surface of the circuit board and is formed to be larger than the first inclined portion; wherein the second inclined portion is formed to be larger than the first inclined portion in a thickness direction of the circuit board; wherein a width of the first inclined portion is formed to be smaller than a width of the second inclined portion; wherein the front surface and side surfaces of the circuit board is sealed with sealing resin; wherein the first inclined portion and the second inclined portions are sealed with the sealing resin; wherein the conductive pattern is formed within 2 mm from the end part of the circuit board on the surface of the circuit board; and wherein the first inclined portion and the second inclined portion are located on the peripheral portion of the circuit board.
