The surface may support the vicinity of both ends of the external relay substrate h. That is, it is sufficient that the support portion for supporting the external relay substrate h is formed at a predetermined height of the accommodation space in the filter substrate case 14, and as in the present embodiment, the protrusion end surface 20a and the surface of the lower edge 21a are not necessarily provided. There is no need to support it.
[0032]
However, if the external relay substrate h (second substrate) is supported by the projecting end surface 20a and the lower edge 21a of the opening 21 as in the present embodiment, the external relay substrate is formed by both the bottom member 18 and the lid member 19. Since h is supported, it is possible to easily check the assembling property of both members. That is, if the bottom member 18 and the lid member 19 are not assembled correctly, the positions of the projecting end surface 20a and the lower edge 21a are relatively displaced, and the external relay board h cannot be supported. In the state where the external relay substrate h is accurately supported, it can be confirmed that the assembly of both members is performed accurately.
