To provide a joint method that can achieve a joint body with high joint strength.SOLUTION: The joint method includes steps of: forming an uneven shape, in which a ratio of a depth from a tip portion of a convex part to a base end part thereof and a width of the tip portion of the convex part is 10:1 or more, in a first metal member; and jointing the first metal member to a second metal member by giving vibrations along a protruding direction of the convex part to the first metal member while pressurizing the first metal member and the second metal member which are superposed on each other, with the tip portion of the convex part in the uneven shape contacted with a portion to be jointed of the second metal member, along the protruding direction of the convex part.SELECTED DRAWING: Figure 1 【課題】高い接合強度の接合体が得られる接合方法を提供すること。【解決手段】接合方法は、第１金属部材に凸部の先端部から基端部までの深さと、凸部の先端部の幅と、の比が１０：１以上となる凹凸形状を形成するステップと、凹凸形状の凸部の先端部を第２金属部材の被接合部に当接させた状態で重ね合わせた第１金属部材および第２金属部材を凸部が突出する方向に沿って加圧しながら、第１金属部材に対して凸部が突出する方向に沿った振動を与えて第１金属部材を第２金属部材に接合するステップと、を有する。【選択図】図１
