1. An electrically operated valve comprising:
a valve main body having a valve chamber communicated with an inflow passage introducing a refrigerant and an outflow passage discharging the refrigerant;
a valve body for changing a flow rate of the refrigerant by moving forward and backward with respect to a valve seat formed within the valve chamber between a valve close state seating on the valve seat and a valve open state separating from the valve seat;
an electric motor for driving the valve body;
a control board mounted with electronic components controlling the electric motor;
a board storage portion for making it possible the control board to be stored in a sealed state; and
a connector portion having an external connection terminal for an electrical connection to the outside and a sealing structure sealed by fitting to a mating connector,
wherein the electrically operated valve further comprises:
a communicating passage for communicating the board storage portion with the connector portion; and
a terminal coating molded portion formed in an inner side of the connector portion covers and supports an intermediate portion of an external connecting terminal,
the communicating passage is formed in the terminal coating molded portion,
wherein the board storage portion includes:
a case portion having an opening for making them possible the control board to be stored in an internal portion thereof and the board to be installed in the internal portion thereof; and
a lid body for occluding the opening, and
wherein the board storage portion comes to the sealed state when the mating connector is fitted to the connector portion.
