The first and second cases include first and second opposed portions opposed to the first and second substrates outside the first and second recess, respectively. A spacer for setting distance between the first opposed portion and the second opposed portion is provided. The spacer sets the distance between the first and second opposed portions to be longer than distance between the outer surface of the first substrate and the outer surface of the second substrate.
