To provide a technology etc. which enables improvement of efficiency of driving of a diaphragm pump.SOLUTION: A diaphragm pump according to the present technology includes a first diaphragm, a second diaphragm, and an adjustment portion. The first diaphragm includes a first member including a first elastic portion, and a first drive unit that elastically deforms the first elastic portion by drive of the first drive unit. The second diaphragm includes a second member that includes a second elastic portion and forms a space, in which a fluid flows, with the first member, and a second drive unit that elastically deforms the second elastic portion. The adjustment portion is provided in at least one of the first diaphragm or the second diaphragm and adjusts a resonant frequency of the at least one of the first diaphragm or the second diaphragm.SELECTED DRAWING: Figure 1 【課題】ダイヤフラムポンプの駆動の効率を向上させるこができる技術等を提供すること。【解決手段】本技術に係るダイヤフラムポンプは、第１のダイヤフラムと、第２のダイヤフラムと、調整部とを具備する。前記第１のダイヤフラムは、第１の弾性部を含む第１の部材と、その駆動により前記第１の弾性部を弾性変形させる第１の駆動部とを有する。前記第２のダイヤフラムは、第２の弾性部を含み、前記第１の部材との間で流体が流れる空間を形成する第２の部材と、前記第２の弾性部を弾性変形させる第２の駆動部とを有する。前記調整部は、前記第１のダイヤフラム又は前記第２のダイヤフラムのうち少なくとも一方に設けられ、前記第１のダイヤフラム又は前記第２のダイヤフラムのうち少なくとも一方の共振周波数を調整する。【選択図】図１
