The invention relates to a hydraulic modulator having a hydraulic modulator block including a reservoir and a damper; and an electronic control block detachably attached to the surface of the hydraulic modulator block. The reservoir and the damper are overlapped with each other such that a surface of the hydraulic modulator block becomes entirely substantially flat. With this, the hydraulic modulator becomes simple in construction. The invention further relates to a hydraulic modulator having a solenoid valve; an electronic control circuit board; and an electric wiring pattern prepared by pressing a metal plate having a first major surface formed with a first tin layer and a nickel layer and a second major surface formed with a second tin layer, into a three-dimensional shape such that the electric wiring pattern is formed with (1) a first terminal having a surface that is formed with the first or second tin layer electrically connected with the solenoid valve, (2) a connector terminal having first and second surfaces respectively formed with the first and second tin layers, and (3) a second terminal having a surface that is formed with the nickel layer electrically connected with the electronic control circuit board. Thus, each terminal has a secure electrical connection with another member.
