ABSTRACT:
A soft adhesive agent whose force occurring at the time of curing is small is applied between a rib and a PD, and after the curing of the soft adhesive agent, a hard adhesive agent whose force occurring at the time of curing is large is applied between the rib and a plate. Thus since a sensor portion is fixed to a main-body base with two kinds of adhesive agents including the soft adhesive agent and the hard adhesive agent, it is possible to suppress the positional offset of the sensor portion at the time of its attachment, and it is possible to sufficiently ensure reliability with respect to the temperature change as well.
