Abstract
During joining, while the inversion plate is inserted in a recessed portion of the connecting member and an opening of the recessed portion faces upward in a vertical direction, a boundary at which an inner wall surface of the recessed portion faces an outer side surface of the inversion plate is continuously radiated with a laser beam from above by one round or more. The inner wall surface in a circular shape of the connecting member is an inclined surface inclined further apart from the outer side surface of the inversion plate as the inclined surface is located closer to the laser beam radiation side, and the inclined surface satisfies w/(h·D)≥0.002 (w: a length of the inclined surface in a radial direction, h: a height of the inclined surface, D: a diameter of the inclined surface on an opposite side to the laser beam radiation side).
