PROBLEM TO BE SOLVED: To prevent a short-circuiting, leak or the like between electrodes by improving a sealing characteristic and to reduce an operation force in connecting connectors. SOLUTION: Each external terminal 3 of a second connector is inserted into a external terminal insertion hole 13a of a sealing member 13 embedded in an end face S1 of a fitting projection part of a first connector and thereby, a bulged part 13b is formed on the external terminal insertion side in the vicinity of the external terminal insertion hole 13a throughout its entire circumference. Alternatively, the bulged part is previously formed on the external terminal insertion side in the vicinity of the external terminal insertion hole throughout its entire circumference, and an inter-electrode sealing part M and a butt surface sealing part N are locally formed by butting the end face S1 of the fitting projection part against the bottom face part S2 of a fitting recessed part 12a.
