置かれるようになってきた。2. Description of the Related Art For example, a disc brake is used as a braking device for an automobile or the like, and there is a disc brake pad as a braking member. At present, the mainstream of disc brake pads has a configuration in which a friction member made of an organic composite material is bonded on a back metal via an adhesive. The disc brake pad is a member that is pressed by a rotating disc rotor and exchanges kinetic energy into frictional heat by the frictional force to perform braking. In recent years, the shearing force and frictional heat applied to the disc brake pads tend to increase with the improvement of the power performance of automobiles and the adoption of FFs, and tire wheels with a wide gap are mounted for the purpose of improving cooling performance. As a result, it has become directly susceptible to the effects of rainwater and snow melting agents. As a result, disc brake pads have come under very severe conditions in mechanical strength and corrosion conditions.

じていた。On the other hand, the disc brake pad is an important security component, and in particular, the bonding surface between the back metal and the friction material needs to have an adhesive strength that does not break at all. For this reason, conventional disc brake pads have been subjected to various treatments on the back metal for the purpose of improving the adhesion between the back metal and the friction member and improving the rust prevention of the back metal. For example, JP-B-57-45939, JP-A-51-24533, and JP-A-59-1.
Although there is a method disclosed in Japanese Patent No. 44836, there is no remarkable rust-preventing effect enough to satisfy the reliability required for a disc brake pad, or a rust-preventing effect can be expected, but safety, hygiene and pollution points of view. Had difficulty in handling.

認した。As shown in Table 2, it can be seen that the disc brake pads obtained in Examples 1 and 2 did not generate rust and had excellent adhesive strength. On the other hand, the disc brake pad obtained in Comparative Example 1 did not cause any problem with respect to the adhesive strength, but it was confirmed that 10% of rust was generated.
