• and
• a device accommodating unit accommodating a device connected to the circuit substrate,
• wherein the resin molded body is an integral molded product made of resin,
• wherein a connecting portion has a plate shape extending outwards from the inner wall of the connector unit, and a second thickness thinner than a first thickness of the inner wall,
• wherein the connecting portion is linked to the device accommodating unit,
• wherein the inner wall of the connector unit has a thin wall portion disposed at a position between the side walls in a vicinity of a connecting position where the inner wall and the connecting portion are connected to each other, and
