Abstract
A substrate is obtained as follows. A structure is formed using a metal plate for a lead frame on which terminals and connection portions are formed; the terminals are exposed from either a front or back surface and the connection portions connect the terminals together. A resin is then used to make the structure hard. The height of a step in a central step portion is variable. The resin is one of PA6T, PPS, and LCP, all of which are resistant to heat. A step portion can be obtained which projects from a bottom surface of a circuit substrate. The circuit substrate is inexpensively obtained.
