Document Type and Number:
Japanese Patent JP7251971
Kind Code:
B2
Abstract:
To provide an electronic control device equipped with a circuit board having high durability against fastening force of a fastening member.SOLUTION: An elastic modulus of an outermost layer (51) of a circuit board (20) is lower than an elastic modulus of an adjacent layer (53) adjacent to the outermost layer (51). The outermost layer (51) has a contact portion (56) that is brought into contact with the fastening surface (43) of a fastening member (40). The contact portion (56) is provided with a metal holder (72) extending in a thickness direction of the circuit board (20) to hold a thickness of the outermost layer (51). One end (78) of the holder (72) projects from a surface (51a) of the outermost layer (51) and is brought into contact with the fastening surface (43) of the fastening member (40). The other end (76) of the holder (72) reaches at least a boundary (57) between the outermost layer (51) and an adjacent layer (53).SELECTED DRAWING: Figure 2
