PROBLEM TO BE SOLVED: To provide a joint structure easy for assembling. SOLUTION: A battery 13 is fixed on a circuit substrate 11 by locking a locking part 25 of a joint member 24 into an aperture 28 of the circuit substrate 11, and fixing part 27 is fixed on the circuit substrate 11 by a screw 29. A first electrode 14 of the battery 13 is contacted with a first terminal part 16 of the circuit substrate 11, a second electrode 15 of the battery 13 is contacted with a contacting part 26 of the joint member 24, then the fixing part 27 of the joint member 24 is contacted with the second terminal part 30 of the circuit substrate 11. |
