To provide a manufacturing method for a motor capable of improving sealability between a first housing and a second housing.SOLUTION: A manufacturing method for a motor provided with a housing comprising a first housing, and a second housing fixed to the first housing by bringing an edge portion of a second opening into contact with an edge portion of a first opening 21a, comprises: a liquid gasket part formation step of forming a liquid gasket part arranged in at least a part of a portion including the edge portion of the first opening 21a by coating a liquid gasket; and an attachment step of attaching the second housing onto the first housing by causing the edge portion of the first opening 21a and the edge portion of the second opening to bring into contact with each other via the liquid gasket part. The liquid gasket part has a shape where a part of an annular shape in a circumferential direction is partitioned via an air gap portion. In the attachment step, the liquid gasket part is pushed and expanded; and portions partitioned via the air gap portion, out of the liquid gasket part are connected to each other to form a first annular gasket part having the annular shape in the circumferential direction.SELECTED DRAWING: Figure 9 【課題】第１ハウジングと第２ハウジングとの間の封止性を向上できるモータの製造方法の提供。【解決手段】第１ハウジングと、第２開口部の縁部が第１開口部２１ａの縁部と接触して第１ハウジングに固定される第２ハウジングと、を有するハウジングを備えるモータの製造方法であって、液状のガスケットを塗布し、少なくとも一部が第１開口部２１ａの縁部を含む部分に配置される液状ガスケット部を形成する液状ガスケット部形成工程と、第１開口部２１ａの縁部と第２開口部の縁部とを液状ガスケット部を介して接触させて、第２ハウジングを第１ハウジングに取り付ける取付工程と、を含む。液状ガスケット部は、周方向に沿った環状の一部が空隙部を介して分断された形状である。取付工程においては、液状ガスケット部を押し広げて、液状ガスケット部のうち空隙部を介して分断された部分同士を繋ぎ、周方向に沿った環状の第１環状ガスケット部を形成する。【選択図】図９
