Abstract: A frame includes first and second leads and a body. The first and second leads contain a metal material. The body contains a non-metal material and has first and second side surfaces. The first and second leads are covered with the body. The first and second leads extend in a first direction to outwardly protrude from the body. The first and second side surfaces are respectively abutted against two ends of the protruding first lead and respectively slanted to the two ends of the protruding first lead by a first angle θ1 and a second angle θ2, which are defined by the following relationship, θ1≠0° and the θ1≠180°, and the θ2≠0° and the θ2≠180°. The substance between any two points in each of the first and second side surfaces is non-metal.
