Abstract
A method includes providing a first plate for a front wall that defines a front surface of a recess to accommodate a laser diode, a second plate for a rear wall that defines a rear side of the recess, and a third plate for a main body that defines an upper side and lateral sides of the recess and is connected to the front wall and the rear wall. The third plate has through-holes arranged in a first direction and in a second directions orthogonal to the first direction. The plates are bonded together to produce a stacked body. The stacked body is cut along the first direction and the second direction to produce a plurality of caps from the stacked body. When cutting the stacked body along the first direction, a first incision is made along inner wall surfaces of through-holes adjacent along the first direction.
