Abstract: An electronic component includes an element body and at least one external electrode thereon. The element body has a dielectric and inner electrodes. Each external electrode includes a base layer connected to at least one the inner electrode. The base layer is formed on a plurality of surfaces of the element body and contains a metal and a first co-material mixed with the metal. Each external electrode also includes a plating layer formed on at least one face of the base layer. Each external electrode also includes an oxide layer formed on one or more faces of the base layer other than those faces of the base layer on which the plating layer is formed. The oxide layer has a surface layer made from an oxide film of the metal of the base layer and a second co-material.

Abstract: A pneumatic tire includes two circumferential main grooves disposed in an inner half of a tread developed width in a tire lateral direction; shoulder lug grooves that divide shoulder land portions into shoulder block portions and that each include a see-through portion in the tire lateral direction; and center lug grooves that divide a center land portion into a plurality of center block portions. The center lug grooves each include: two end groove portions opening to the innermost circumferential main grooves and one center groove portion that extends between the end groove portions, has at least a part disposed on a tire equator line, and has an angle ?1 with respect to the tire equator line satisfying ?45°??1?+15°.

Abstract: A pneumatic tire rotatable around a tire rotation axis includes a tread portion provided with a circumferential main groove extending in a tire circumferential direction, and a projecting body provided on a groove bottom of the circumferential main groove and projecting outward from the groove bottom in a tire radial direction. The projecting body includes a first portion connected to the groove bottom and a second portion disposed outward from the first portion in the tire radial direction. In a tire lateral direction, a dimension of the first portion is W1 and a dimension of the second portion is W2, and a condition W1<W2 is satisfied.

Abstract: A tread surface of a tread portion of a pneumatic tire comprises a circumferential main groove and a projection body extending continuously in a tire circumferential direction, the projection body projecting in a tire radial direction from a groove bottom of the circumferential main groove; and connecting portions connecting the projection body and groove walls of the circumferential main groove alternately disposed in the tire circumferential direction on first and second sides of the projection body in a tire lateral direction; a relationship of L to a total of V1 to Vn and W1 to Wn satisfying from 0.7 L to 1.5 L, where L is a circumferential length of the projection body, and V1 to Vn and W1 to Wn are circumferential dimensions of the connecting portions on the first and second sides of the projection body in the tire lateral direction, respectively.
