Stacked core manufacturing method and stacked core manufacturing apparatus

A stacked core manufacturing method comprising:

• punching a steel plate from a material to which an adhesive has been applied;
• sequentially stacking a plurality of the steel plates that have been punched out, and forming a first bonding layer to fix the steel plates adjacent to each other in a stacking direction of the plurality of the steel plates, by the adhesive sandwiched between the steel plates;
• and
• forming a second bonding layer to fix the plurality of the steel plates to one another, on a side surface that is a surface formed by each end surface of the plurality of the steel plates in a stacked body in which the plurality of the steel plates are stacked, by applying a force in the stacking direction to the stacked body to cause the adhesive to protrude from between the steel plates, and causing the adhesive to spread in the stacking direction on the side surface, wherein
• in forming the first bonding layer, the adhesive is spread in a part of an area of a plate surface on which the first bonding layer is formed in the steel plates, and
• in forming the second bonding layer, the adhesive is caused to protrude from a portion in the area in a contour of the steel plate,
• in a holder to hold the stacked body in forming the first bonding layer and forming the second bonding layer, there is provided a holding block to hold the stacked body by coming into contact with the stacked body from a direction perpendicular to the stacking direction, and
• in forming the second bonding layer, the second bonding layer is formed by causing the adhesive to protrude in a blank part adjacent to the area, the blank part being a space where the holding block is not provided in a periphery of the stacked body.
