To include a control board; a connector including a terminal connected to the control board; and a housing case to which the control board and the connector are fixed. The control board has a part sealed with a sealing resin. The connector is disposed at a position facing another part of the control board, being isolated from the sealing resin by the control board and the housing case. ## Claims ### Claim 1 An electronic control device comprising: a control board that has a part sealed with a sealing resin; a connector that is disposed at a position facing another part of the control board and includes a terminal connected to the control board; a housing case to which the control board and the connector are fixed, wherein the housing case includes: a first frame which surrounds the connector and comes into contact with the control board, and a second frame which comes into contact with the control board outside the first frame; a first resin-unsealed space formed by the control board, the housing case and the connector, wherein the first resin-unsealed space is not being sealed with the sealing resin; a second resin-unsealed space which is not affected by an ingress of the sealing resin between the housing case, the second frame, and the control board; and an adhesive seal material at contact portions between the first frame and the control board, and the second frame and the control board; wherein the connector is isolated from the sealing resin by the control board and the housing case. ### Claim 2 (depends on 1) The electronic control device according to claim 1, wherein the first frame includes a member different from the housing case. ### Claim 3 (depends on 1) The electronic control device according to claim 1, wherein the control board has another part mounted on the second resin-unsealed space. ### Claim 4 (depends on 3) The electronic control device according to claim 3, wherein the connector includes a connector housing provided with a second through hole that links the resin-unsealed space with outside air, and the second through hole is provided with a breathing filter membrane which has air permeability but not water permeability. ### Claim 5 (depends on 4) The electronic control device according to claim 4, wherein the connector housing of the connector has a shape corresponding to a shape of an electronic component disposed in the resin-unsealed space. ### Claim 6 (depends on 3) The electronic control device according to claim 3, wherein the control board has a part which is mounted on the resin-unsealed space and higher than the other part of the control board mounted on the second resin-unsealed space. ### Claim 7 (depends on 1) The electronic control device according to claim 1, wherein the sealing resin is a thermosetting resin. ### Claim 8 An electronic control device comprising: a control board that has a part sealed with a sealing resin; a connector hat is disposed at a position facing another part of the control board and includes a terminal connected to the control board; and a housing case to which the control board and the connector are fixed, wherein the housing case includes a first frame which surrounds the connector and comes into contact with the control board, and a second frame which comes into contact with the control board outside the first frame; a resin-unsealed space formed from the control board, the housing case and the connector, wherein the resin-unsealed space not being sealed with resin; an adhesive seal material at contact portions between the first frame and the control board, and the second frame and the control board, wherein the connector is isolated from the sealing resin by the control board and the housing case. ### Claim 9 (depends on 8) The electronic control device according to claim 8, wherein the control board has a part mounted on the resin-unsealed space. ### Claim 10 (depends on 9) The electronic control device according to claim 9, wherein the sealing resin is a thermosetting resin. ### Claim 11 (depends on 8) The electronic control device according to claim 8, wherein the housing case is provided with a first through hole that links the resin-unsealed space with outside air, and the first through hole is provided with a breathing filter assembly which has air permeability but not water permeability. ### Claim 12 (depends on 8) The electronic control device according to claim 8, wherein the sealing resin is a thermosetting resin. ### Claim 13 An electronic control device comprising: a housing case to which a control board and a connector are fixed, wherein the housing case includes: a first frame which surrounds the connector and comes into contact with the control board, and a second frame which comes into contact with the control board outside the first frame; a first resin-unsealed space formed by the control board, the housing case and the connector, wherein the first resin-unsealed space is not being sealed with a sealing resin; an adhesive seal material at contact portions between the first frame and the control board, and the second frame and the control board; a connector holding unit provided with a gap between the connector and the control board so as to hold the connector in the housing case; and a resin-ingress prevention unit which cooperates with the control board to prevent ingress of the sealing resin into the gap, wherein the connector is isolated from the sealing resin by the control board and the housing case.
