 a plurality of board-holding units which are inserted and fitted to a plurality of mounting holes formed at the board, so that the board is attached to the case, 
   wherein the board-holding units include:
 a connector side board-holding unit provided at a position on the connector housing side of the connection portion; and 
 a solenoid side board-holding unit provided at a position on the solenoid housing side of the connection portion. 
   
   
   
       2 . The fluid pressure control device according to  claim 1 , wherein a part of the solenoid side board-holding unit to be inserted and fitted to a corresponding one of the mounting holes is elastically deformable toward the center of the mounting hole. 
   
   
       3 . The fluid pressure control device according to  claim 2 , wherein the solenoid side board-holding unit is divided into a plurality of pieces by a slit extending orthogonally to the board. 
   
   
       4 . The fluid pressure control device according to  claim 1 , wherein:
 the solenoid housing, the connection portion, and the connector housing are aligned in a reference direction; and   wherein the solenoid side board-holding unit is disposed at a position in the solenoid housing, and the position is farther from the connector housing than the center of the solenoid housing in the reference direction is.   
   
   
       5 . The fluid pressure control device according to  claim 1 ,
 wherein a mounting-hole distance is smaller than a holding-unit distance, provided that:   one of the mounting holes to which the connector side board-holding unit is inserted and fitted is a connector side mounting hole, and another one of the mounting holes to which the solenoid side board-holding unit is inserted and fitted is a solenoid side mounting hole;   the mounting-hole distance is a distance between a position at a periphery of the connector side mounting hole, the position being farthest from the solenoid side mounting hole, and a position at a periphery of the solenoid side mounting hole, the position being farthest from the connector side mounting hole, and   the holding-unit distance is a distance between a position at an outer peripheral surface of the connector side board-holding unit, the position being farthest from the solenoid side board-holding unit, and a position at an outer peripheral surface of the solenoid side board-holding unit, the position being farthest from the connector side board-holding unit.   
   
   
       6 . The fluid pressure control device according to  claim 1 , wherein the connector side board-holding unit is press-fitted to a corresponding one of the mounting holes. 
   
   
       7 . The fluid pressure control device according to  claim 1 , wherein the connector side board-holding unit is divided into a plurality of pieces by a slit extending orthogonally to the board. 
   
   
       8 . The fluid pressure control device according to  claim 1 , wherein the connector side board-holding unit is the only member of the board-holding units provided at a position on the connector housing side of the connection portion. 
   
   
       9 . The fluid pressure control device according to  claim 1 , wherein the board-holding units includes a plurality of units provided at positions on the connector housing side of the connection portion, the plurality of units including the connector side board-holding unit. 
   
   
       10 . The fluid pressure control device according to  claim 1 , wherein:
 the solenoid side board-holding unit is the only member of the board-holding units provided at a position on the solenoid housing side of the connection portion; and   the solenoid side board-holding unit has a convex portion which prevents the solenoid side board-holding unit from slipping out of a corresponding one of the mounting holes of the board.   
   
   
       11 . The fluid pressure control device according to  claim 9 , wherein:
 the solenoid side board-holding unit is the only member of the board-holding units provided at a position on the solenoid housing side of the connection portion; and   the solenoid side board-holding unit has a convex portion which prevents the solenoid side board-holding unit from slipping out of a corresponding one of the mounting holes of the board.   
   
   
       12 . The fluid pressure control device according to  claim 1 , wherein the fluid pressure control device is mounted on a vehicle, and brake fluid flows through the fluid channel.
