A first connector has a housing holding a female contact. A second connector has a housing holding a male contact. The connectors are connected to each other by inserting the male contact into the female contact along an insertion direction. The female contact has a support portion and a spring portion having a contact point. The spring portion is located above the support portion in the vertical direction. The male contact is insertable between the spring portion and the support portion. The male contact has a contact portion, a tip, an upper slope and a lower slope. The contact portion contacts the contact point when the male contact is inserted into the female contact. The upper slope extends from the tip to the contact portion, sloping over a first tapering range. The lower slope extends from the tip to the contact portion, sloping over a shorter second tapering range.
