PROBLEM TO BE SOLVED: To save a space for a substrate and perform alignment adjustment between connection terminals accurately in a short time.SOLUTION: First connection terminals 28 are formed in a light-transmissive substrate 22, light-reflective second connection terminals 18 which are to be connected to the first connection terminals 28 and has an area larger than the first connection terminals 28 are formed on a connection target 12. The light-transmissive substrate 22 is arranged on the connection target 12, the first connection terminals 28 are placed above the second connection terminal 18, light is radiated from the light-transmissive substrate 22 side, alignment of the light-transmissive substrate 22 and the connection target 12 is performed such that reflected light from the second connection terminals 18 passes through the periphery of the first connection terminals 28, and the aligned light-transmissive substrate 22 and connection target 12 are connected. |
