The present invention proposes a vehicle brake fluid pressure control device (10), which comprises a base body (40) provided with a brake fluid line (A1 - E2), a housing (36) in which a control board (99) is accommodated, and a cover (38) that is attached to the housing (36) and covers the control board (99). The housing (36) has an opening on a front side and an opening on a back side and has a peripheral wall part (84) in which the control board (99) is accommodated. The peripheral wall part (84) of the housing (36) has an attachment part (36a) to which the cover (38) is attached. The cover (38) has a protrusion (38a) extending toward the attachment part (36a). The attachment part (36a) of the peripheral wall part (84) has a top groove (36c) that is filled with an adhesive (36b) and into which the protrusion (38a) is inserted, The cover (38) comes in contact with the attachment part (36a) at a contacting part (39) present on an outer side of the protrusion (38a) when the cover (38) is attached to the housing (36). At least one of the top groove (36c) of the attachment part (36a) and a portion between the contacting part (39) and the protrusion (38a) of the cover (38) has a collecting groove (38b) in which an excess portion of the adhesive (36b) is collected when the cover (38) is attached to the housing (36). The housing (36) has a flange (92) that comes in contact with the base body (40). The flange (92) overhangs toward an outer side from a peripheral wall part (84) of the housing (36). The flange (92) has a lower groove (92b) to be filled with an adhesive (36b). A surface of the flange (92) close to the base body (40) is divided by the lower groove (92b) into an outer-side surface (92e) on an outer side of the lower groove (92b) and an inner-side surface (92f) on an inner side of the lower groove (92b). A small gap (92g) is ensured between the inner-side surface and the base body (40) when the outer-side surface comes in contact with the base body (40). An excess portion of the adhesive (36b) flows into the small gap (92g).
