A substrate includes a first pattern on which terminals are formed; a second pattern on which terminals are formed; and a third pattern on which terminals are formed. A distance between a first pair of terminals which are configured by one terminal of the first pattern and one terminal of the second pattern is equal to a distance between a second pair of terminals which are configured by another terminal of the first pattern and one terminal of the third pattern, and a distance between a third pair of terminals which are configured by another of the terminals of the third pattern and another of the terminals of the second pattern is equal to a distance between a fourth pair of terminals which are configured by the other of the terminal of the third pattern and the other of the terminal of the first pattern.
