A lead frame and a light-emitting packaging element are disclosed. The lead frame includes a lead frame and a plurality of lead frame units located within the lead frame and integrally connected to it, arranged periodically and interconnected. Each lead frame unit includes a chip mount and a connecting unit. The chip mount has a first electrode pad and a second electrode pad spaced apart along a first direction. The connecting unit is used to connect the lead frame and the chip mount integrally. The first electrode pad and the second electrode pad each have a top surface and a bottom surface facing away from each other, and a peripheral surface connecting the top surface and the bottom surface. At least one of the first electrode pads and the second electrode pad has a wave-shaped structural unit on its peripheral surface. The wave-shaped structural unit on at least one of the first electrode pads and the second electrode pad provides stress resistance in different directions, thereby improving the structural strength of the light-emitting packaging element.

The invention provides a method for manufacturing a reactor and a reactor, wherein a molded core and a molded coil are firmly jointed, and a welding part of a bus bar and a lead wire is prevented from being damaged. A method for manufacturing a reactor includes: a bonding step of bonding a molded core and a molded coil with an adhesive; and a welding step in which the lead wire of the coil is connected to the bus bar fixed to the mold core by welding. The coil is attached to the leg portion. The bonding step includes: a coating step in which an adhesive is applied to the bonding surface of the leg portion of the core member and the inner peripheral surface of the yoke portion of the core member; a pressing step for pressing and spreading the applied adhesive; and a hardening step for hardening the adhesive. In the pressing step, the adhesive applied to the bonding surface is pressed and spread out to be extruded to at least one of the upper surface and the lower surface of the leg part, and extruded to at least one of the inner side surface of the leg part and the outer side surface opposite to the inner side surface of the leg part, which are the surfaces of the leg part facing each other, and the adhesive is attached to the molded coil.
