An endoscope treatment tool includes a sheath having electric insulation; and an electrode unit provided at a distal end portion of the sheath. The present invention relates to a multi-piece solid golf ball comprising a core consisting of a center and an intermediate layer, and a cover, wherein the center has a diameter of 25 to 40 mm, and a surface hardness is higher than a central point hardness of the center by not less than 15, the intermediate layer has a thickness of 0. A first resistor and a first capacitor are coupled in series between a first input terminal of the amplifier and the line, and a second resistor and a second capacitor are coupled in series between a second input terminal of the amplifier and the line. The frequency dependent load is adjusted based on the frequency response setting.
